Groups and projects are synonymous terms. Your {GROUP-ID}
is the
same as your project ID. For existing groups, your group/project ID
remains the same. The resource and corresponding endpoints use the
term groups
.
This feature is not available for M0
free clusters, M2
, and
M5
clusters. To learn more about which features are unavailable,
see Atlas M0 (Free Cluster), M2, and M5 Limitations.
The Atlas Administration API authenticates using HTTP Digest Authentication. Provide a programmatic API public key and corresponding private key as the username and password when constructing the HTTP request. To learn how to configure API access for an Atlas project, see Get Started with the Atlas Administration API.
Considerations¶
Clusters can span regions and cloud service providers. The total number of nodes in clusters spanning across regions has a specific constraint on a per-project basis.
Atlas limits the total number of nodes in other regions in one project to a total of 40. This total excludes:
- Google Cloud regions communicating with each other
- Free clusters or shared clusters
The total number of nodes between any two regions must meet this constraint.
If an Atlas project has nodes in clusters spread across three regions:
- 30 nodes in Region A
- 10 nodes in Region B
- 5 nodes in Region C
You can only add 5 more nodes to Region C because:
- If you exclude Region C, Region A + Region B = 40.
- If you exclude Region B, Region A + Region C = 35, <= 40.
- If you exclude Region A, Region B + Region C = 15, <= 40.
Each combination of regions with the added 5 nodes still meets the per-project constraint:
- Region A + B = 40
- Region A + C = 40
- Region B + C = 20
You can't create a multi-region cluster in a project if it has one or more clusters spanning 40 or more nodes in other regions.
Contact Atlas support for questions or assistance with raising this limit.

Request Body Parameters¶
If modifying any of the providerSettings
or replicationSpec
values, you must specify the providerSettings.providerName
.
For M2
and M5
clusters, you must also specify the
providerSettings.backingProviderName
.
You can't modify a paused
cluster other than to resume the
cluster. Nor can you pause a cluster with pending changes.
You do not need to provide all parameters when modifying a cluster, only the parameters you want to change and any parameters required to make that change.
Body Parameter | Type | Necessity | Description | ||||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
autoScaling | object | Optional | Collection of settings that configures auto-scaling information for the cluster. If you specify the autoScaling object, you must also specify the providerSettings.autoScaling object. Tip See also: | ||||||||||||||||||||||
autoScaling.compute | object | Optional | Specifies whether the cluster automatically scales its cluster tier and whether the cluster can scale down. Important Cluster tier auto-scaling is not available for clusters using NVME storage classes. | ||||||||||||||||||||||
autoScaling.compute.enabled | boolean | Optional | Flag that indicates whether cluster tier auto-scaling is enabled. The default is false.
Note If you disable auto-scaling for your cluster, Atlas sets your minimum and maximum autoscaling bounds to null. If you re-enable autoscaling at a later time, you must set new values for providerSettings.autoScaling.compute.minInstanceSize and providerSettings.autoScaling.compute.maxInstanceSize. | ||||||||||||||||||||||
autoScaling.compute.scaleDownEnabled | boolean | Conditional | Flag that indicates whether the cluster tier may scale down. Atlas requires this parameter if "autoScaling.compute.enabled" : true. If you enable this option, specify a value for providerSettings.autoScaling.compute.minInstanceSize. Note To configure this value, you must set | ||||||||||||||||||||||
autoScaling.diskGBEnabled | boolean | Optional | Flag that indicates whether disk auto-scaling is enabled. The default is true.
The maximum amount of RAM for the selected cluster tier and the oplog size can limit storage auto-scaling. To learn more, see Customize Your Storage. | ||||||||||||||||||||||
backupEnabled | boolean | Optional | Flag that indicates whether legacy backups have been enabled. Set to false to disable legacy backups for the cluster. Atlas deletes any stored snapshots. See the legacy backup Snapshot Schedule for more information. You cannot enable legacy backups if you have an existing cluster in the project with Cloud Backups enabled. The default value is false. Note This option is not supported on clusters running MongoDB 4.2. Clusters running MongoDB 4.2 must use Cloud Backups. Important Clusters running MongoDB If you create a new Atlas cluster and set "backupEnabled" : true, the API responds with an error. This change doesn't affect existing clusters that use legacy backups. | ||||||||||||||||||||||
biConnector | object | Optional | Configuration of BI Connector for Atlas on this cluster. The MongoDB Connector for Business Intelligence for Atlas (BI Connector) is only available for The BI Connector is a powerful tool which provides users
SQL-based access to their MongoDB databases. As a result, the
BI Connector performs operations which may be CPU and memory
intensive. Given the limited hardware resources on | ||||||||||||||||||||||
biConnector.enabled | boolean | Optional | Flag that indicates whether or not BI Connector for Atlas is enabled on the cluster.
| ||||||||||||||||||||||
biConnector.readPreference | string | Optional | Source from which the BI Connector for Atlas reads data. Each BI Connector for Atlas read preference contains a distinct combination of readPreference and readPreferenceTags options. Tip See also:
Note To set the readPreference value to "analytics", the cluster must have at least one analytics node. If the readPreference value is "analytics", you cannot remove all analytics nodes from the cluster. | ||||||||||||||||||||||
clusterType | string | Conditional | Type of the cluster that you want to modify. You cannot convert a sharded cluster deployment to a replica set deployment. Note When should you use clusterType?
Atlas accepts:
| ||||||||||||||||||||||
diskSizeGB | number | Conditional | Capacity, in gigabytes, of the host's root volume. Increase this number to add capacity, up to a maximum possible value of 4096 (4 TB). This value must be a positive integer. Note When should you use diskSizeGB? This setting:
The minimum disk size for dedicated clusters is 10 GB for AWS and Google Cloud, and 32 GB for Azure. If you specify diskSizeGB with a lower disk size, Atlas defaults to the minimum disk size value. Each cluster tier has its own default value. If you set a value below the cluster default, Atlas replaces it with the default value. To view default values: open the Atlas web interface; click the button to add a new cluster; view the available default sizes; close the window without saving changes. Important Atlas calculates storage charges differently depending on whether you choose the default value or a custom value. For details, see Storage Capacity. The maximum value for disk storage cannot exceed 50 times the maximum RAM for the selected cluster. If you require additional storage space beyond this limitation, consider upgrading your cluster to a higher tier. Note When you increase the storage capacity of a cluster, Atlas increases the cluster's oplog size. Atlas scales the oplog to 5% of the cluster capacity, not to exceed 50 GB. NVMe storage requires an oplog which is 10% of the storage capacity. Atlas doesn't change the oplog size if it exceeds 5% of the new storage capacity (10% in the case of NVMe storage). As cluster storage capacity decreases, Atlas doesn't change the oplog size unless it exceeds a certain maximum determined according to MongoDB best practices. | ||||||||||||||||||||||
encryptionAtRestProvider | string | Optional | Cloud service provider that offers Encryption at Rest. | ||||||||||||||||||||||
labels | array of objects | Optional | Collection of key-value pairs that tag and categorize the cluster. Each key and value has a maximum length of 255 characters.
| ||||||||||||||||||||||
mongoDBMajorVersion | string | Optional | Version of the cluster to deploy. Atlas supports the following MongoDB versions for M10+ clusters:
You must deploy MongoDB 4.4 if "providerSettings.instanceSizeName" : "M2" or "M5". Atlas always deploys the cluster with the latest stable release of the specified version. You can upgrade to a newer version of MongoDB when you modify a cluster Note If you are upgrading from version 4.0 to 4.2 and you have legacy backups enabled, you must set backupEnabled to false and set providerBackupEnabled to true as part of the API request. Continuous backups are no longer supported in MongoDB version 4.2. Instead, use Cloud Backups. If mongoDBMajorVersion is set to CONTINUOUS, you must omit the mongoDBMajorVersion field. You can't modify the MongoDB version that you clusters run when you choose the continuous release cadence. | ||||||||||||||||||||||
name | string | Optional | Name of the cluster as it appears in Atlas. After Atlas
creates the cluster, you can't change its name. | ||||||||||||||||||||||
numShards | number | Conditional | Positive integer that specifies the number of shards to deploy for a sharded cluster. Important If you use the replicationSpecs parameter, you must set numShards. Atlas accepts 1 through 50, inclusive. The default value is 1.
Don't create a sharded cluster with a single shard for production environments. Single-shard sharded clusters don't provide the same benefits as multi-shard configurations. For more information on sharded clusters, see Sharding in the MongoDB manual. For details on how this setting affects costs, see Number of Nodes. Note Do not include in the request body for Global Clusters. | ||||||||||||||||||||||
paused | boolean | Optional | Indicates whether the cluster is paused or not. The default value is false. You cannot create a paused cluster. Either omit the parameter or explicitly set to false. | ||||||||||||||||||||||
pitEnabled | boolean | Optional | Indicates if the cluster uses continuous cloud backups. If set to true, providerBackupEnabled
must also be set to true. | ||||||||||||||||||||||
providerBackupEnabled | boolean | Conditional | Set true or false to enable or disable Cloud Backups for cluster backups. If providerBackupEnabled and backupEnabled are false, the cluster does not use Atlas backups. If you disable legacy backups for the cluster, Atlas deletes all stored snapshots. See the legacy backup Snapshot Schedule for more information. You cannot enable Cloud Backups if you have an existing cluster in the project with Legacy Backups enabled. Important You must set this value to true for NVMe clusters. | ||||||||||||||||||||||
providerSettings | object | Optional | Configuration for the provisioned servers on which MongoDB
runs. The available options are specific to the cloud service
provider. | ||||||||||||||||||||||
providerSettings.autoScaling | object | Conditional | Contains the minInstanceSize and maxInstanceSize parameters which specify the range of instance sizes to which your cluster can scale. Atlas requires this parameter if "autoScaling.compute.enabled" : true. Important To configure this value, you must set | ||||||||||||||||||||||
providerSettings.autoScaling.compute | object | Conditional | Range of instance sizes to which your cluster can scale.
Atlas requires this parameter if
"autoScaling.compute.enabled" : true. | ||||||||||||||||||||||
providerSettings.autoScaling.compute.minInstanceSize | string | Conditional | Minimum instance size to which your cluster can automatically
scale (such as M10). Atlas requires this parameter if
"autoScaling.compute.scaleDownEnabled" : true. | ||||||||||||||||||||||
providerSettings.autoScaling.compute.maxInstanceSize | string | Conditional | Maximum instance size to which your cluster can automatically
scale (such as M40). Atlas requires this parameter if
"autoScaling.compute.enabled" : true. | ||||||||||||||||||||||
providerSettings.backingProviderName | string | Conditional | Cloud service provider on which the server for a multi-tenant cluster is provisioned. This setting only works when "providerSetting.providerName" : "TENANT" and "providerSetting.instanceSizeName" : M2 or M5. Atlas accepts the following values:
| ||||||||||||||||||||||
providerSettings.diskIOPS | number | Conditional | Disk IOPS setting for AWS storage. Set only if you selected AWS as your cloud service provider. Maximum input/output operations per second (IOPS) the cluster can perform. The possible values depend on the selected providerSettings.instanceSizeName and diskSizeGB. This setting requires that providerSettings.instanceSizeName to be M30 or greater and cannot be used with clusters with local NVMe SSDs. To view the possible range of IOPS values for the selected instance size and storage capacity:
Click Provision IOPS to see the available IOPS range. If you set the diskIOPS value to a value higher than the default value for the selected volume size, Atlas automatically sets providerSettings.volumeType to PROVISIONED. If you manually set diskIOPS to the default value, you must specify providerSettings.volumeType to be either PROVISIONED or STANDARD. The default value for providerSettings.diskIOPS is the same as the cluster tier's Standard IOPS value, as viewable in the Atlas console. Changing this value affects the cost of running the cluster as described in the billing documentation. Atlas enforces the following minimum ratios for given cluster tiers. This keeps cluster performance consistent with large datasets. Instance sizes M10 to M40 have a ratio of disk capacity to system memory of 60:1. Instance sizes greater than M40 have a ratio of 120:1. Example To support 3 TB (or 3,072 GB) of disk capacity, select a cluster tier with a minimum of 32 GB of RAM. This would be M50 or greater. | ||||||||||||||||||||||
providerSettings.diskTypeName | string | Conditional | Type of disk if you selected Azure as your cloud service provider. Disk type of the server's root volume for Azure instances. If
omitted, Atlas uses the default disk type for the selected
The following table lists the possible values for this field, and their corresponding storage size.
1 Default for 2 Default for 3 Default for 4 Default for | ||||||||||||||||||||||
providerSettings.encryptEBSVolume | boolean | Conditional | Flag that indicates whether the Amazon EBS encryption feature encrypts the host's root volume for both data at rest within the volume and for data moving between the volume and the cluster. Note This setting is always enabled for clusters with local NVMe SSDs. The default value is true. | ||||||||||||||||||||||
providerSettings.instanceSizeName | string | Required | Atlas provides different cluster tiers, each with a default storage capacity and RAM size. The cluster you select is used for all the data-bearing servers in your cluster. Tip See also: M2 and M5 clusters are multi-tenant deployments. You must set providerSettings.providerName to TENANT and specify the cloud service provider in providerSettings.backingProviderName. | ||||||||||||||||||||||
providerSettings.providerName | string | Conditional | Cloud service provider on which Atlas provisions the hosts.
M2 and M5 clusters are multi-tenant deployments. You must set providerSettings.providerName to TENANT and specify the cloud service provider in providerSettings.backingProviderName. | ||||||||||||||||||||||
providerSettings.regionName | string | Conditional | Note Required if setting replicationSpecs array to empty This parameter is required if you have not set any values in the replicationSpecs array. Physical location of your MongoDB cluster. The region you choose can affect network latency for clients accessing your databases. Do not specify this parameter when creating a multi-region cluster using the replicationSpec document. When Atlas deploys a dedicated cluster, Atlas checks if a VPC or VPC connection exists for that provider and region. If not, Atlas creates them as part of the deployment. Atlas assigns the VPC a CIDR block. To limit a new VPC peering connection to one CIDR block and region, create the connection first. Deploy the cluster after the connection starts.
To learn more, see Set up a Network Peering Connection. Select your cloud provider's tab for example cluster region names: | ||||||||||||||||||||||
providerSettings.volumeType | string | Conditional | Disk IOPS setting for AWS storage. Set only if you selected AWS as your cloud service provider. The API resource accepts STANDARD, the default, and PROVISIONED.
| ||||||||||||||||||||||
replicationFactor | number | Optional | Important Use replicationSpecs replicationFactor is deprecated. Use replicationSpecs. Number of replica set members. Each member keeps a copy of your databases, providing high availability and data redundancy. Atlas accepts 3, 5, or 7. The default value is 3. Don't specify this parameter when creating a multi-region cluster using the replicationSpec object. If your cluster is a sharded cluster, each shard is a replica set with the specified replication factor. Atlas ignores this value if you pass the replicationSpec object. | ||||||||||||||||||||||
replicationSpec | object | Optional | Deprecated: Configuration of each region in a multi-region cluster. Each element in this object represents a region where Atlas deploys your cluster. For single-region clusters, you can either specify the providerSettings.regionName and replicationFactor, or you can use the replicationSpec object to define a single region. For multi-region clusters, omit the providerSettings.regionName parameter. For Global Clusters, specify the replicationSpecs parameter rather than a replicationSpec parameter. Important If you use replicationSpec, you must specify a minimum of one replicationSpec.<region> object. Use the replicationSpecs parameter to modify a Global Cluster. Note You cannot specify both the replicationSpec and replicationSpecs parameters in the same request body. | ||||||||||||||||||||||
replicationSpec.<region> | object | Conditional | Important Use replicationSpecs[n].<region> replicationSpec.<region> is deprecated. Use replicationSpecs[n].<region>. Physical location of the region. Replace <region> with the name of the region. Each <region> object describes the region's priority in elections and the number and type of MongoDB nodes Atlas deploys to the region. Important If you use replicationSpec, you must specify a minimum of one replicationSpec.<region> object. Select your cloud service provider's tab for example cluster region names: For each <region> object, you must specify the analyticsNodes, electableNodes, priority, and readOnlyNodes parameters. Tip See also: When Atlas deploys a dedicated cluster, Atlas checks if a VPC or VPC connection exists for that provider and region. If not, Atlas creates them as part of the deployment. Atlas assigns the VPC a CIDR block. To limit a new VPC peering connection to one CIDR block and region, create the connection first. Deploy the cluster after the connection starts.
To learn more, see Set up a Network Peering Connection. | ||||||||||||||||||||||
replicationSpec.<region>.analyticsNodes | number | Optional | Important Use replicationSpecs[n].<region>.analyticsNodes replicationSpec.<region>.analyticsNodes is deprecated. Use replicationSpecs[n].<region>.analyticsNodes. Number of analytics nodes for Atlas to deploy to the region. Analytics nodes are useful for handling analytic data such as reporting queries from BI Connector for Atlas. Analytics nodes are read-only, and can never become the primary. | ||||||||||||||||||||||
replicationSpec.<region>.electableNodes | number | Optional | Important Use replicationSpecs[n].<region>.electableNodes replicationSpec.<region>.electableNodes is deprecated. Use replicationSpecs[n].<region>.electableNodes. Number of electable nodes for Atlas to deploy to the region. Electable nodes can become the primary and can facilitate local reads. The total number of electableNodes across all replicationSpec.<region> object must be 3, 5, or 7. Specify 0 if you do not want any electable nodes in the region. You cannot create electable nodes if the replicationSpec.<region>.priority is 0. | ||||||||||||||||||||||
replicationSpec.<region>.priority | number | Optional | Important Use replicationSpecs[n].<region>.priority replicationSpec.<region>.priority is deprecated. Use replicationSpecs[n].<region>.priority. Election priority of the region. For regions with only replicationSpec.<region>.readOnlyNodes, set this value to 0. For regions where replicationSpec.<region>.electableNodes is at least 1, each replicationSpec.<region> must have a priority of exactly one (1) less than the previous region. The first region must have a priority of 7. The lowest possible priority is 1. The priority 7 region identifies the Preferred Region of the cluster. Atlas places the primary node in the Preferred Region. Priorities 1 through 7 are exclusive: you can't assign a given priority to more than one region per cluster. Example If you have three regions, their priorities would be 7, 6, and 5 respectively. If you added two more regions for supporting electable nodes, the priorities of those regions would be 4 and 3 respectively. | ||||||||||||||||||||||
replicationSpec.<region>.readOnlyNodes | number | Optional | Important Use replicationSpecs[n].<region>.readOnlyNodes replicationSpec.<region>.readOnlyNodes is deprecated. Use replicationSpecs[n].<region>.readOnlyNodes. Number of read-only nodes for Atlas to deploy to the region. Read-only nodes can never become the primary, but can facilitate local-reads. Specify 0 if you do not want any read-only nodes in the region. | ||||||||||||||||||||||

mongoURI | string | Base connection string for the cluster. Atlas only displays this parameter after the cluster is operational, not while it builds the cluster. | ||||||||||||||
mongoURIUpdated | string | Timestamp in ISO 8601 date and time format in UTC when the connection string was last updated. The
connection string changes if you update any of the other values. | ||||||||||||||
mongoURIWithOptions | string | connection string for connecting to the Atlas cluster. Includes the replicaSet, ssl, and authSource query parameters in the connection string with values appropriate for the cluster. To review the connection string format, see the connection string format documentation. To add database users to a Atlas project, see Configure Database Users. Atlas only displays this parameter after the cluster is operational, not while it builds the cluster. | ||||||||||||||
name | string | Name of the cluster as it appears in Atlas. | ||||||||||||||
numShards | number | Positive integer that specifies the number of shards for a sharded cluster. If this is set to 1, the cluster is a replica set. If this is set to 2 or higher, the cluster is a sharded cluster with the number of shards specified. Tip See also: Atlas might return values between 1 and 50. Note Atlas doesn't return this value in the response body for Global Clusters. | ||||||||||||||
paused | boolean | Flag that indicates whether the cluster is paused. | ||||||||||||||
pitEnabled | boolean | Flag that indicates if the cluster uses Continuous Cloud Backup
backups. | ||||||||||||||
providerBackupEnabled | boolean | This applies to dedicated clusters, M10 or greater, only. Flag that indicates if the cluster uses Cloud Backups for backups. If true, the cluster uses Cloud Backups for backups. If providerBackupEnabled and backupEnabled are false, the cluster does not use Atlas backups. | ||||||||||||||
providerSettings | object | Configuration for the provisioned hosts on which MongoDB
runs. The available options are specific to the cloud service
provider. | ||||||||||||||
providerSettings.autoScaling | object | Range of instance sizes to which your cluster can scale. Important You can't specify the providerSettings.autoScaling object if "autoScaling.compute.enabled" : false. | ||||||||||||||
providerSettings.autoScaling.compute | object | Range of instance sizes to which your cluster can scale.
Atlas requires this parameter if
"autoScaling.compute.enabled" : true. | ||||||||||||||
providerSettings.autoScaling.compute.minInstanceSize | string | Minimum instance size to which your cluster can
automatically scale. | ||||||||||||||
providerSettings.autoScaling.compute.maxInstanceSize | string | Maximum instance size to which your cluster can
automatically scale. | ||||||||||||||
providerSettings.backingProviderName | string | Cloud service provider on which the multi-tenant host is provisioned. Atlas returns this parameter only if "providerSettings.providerName" : "TENANT". Atlas can return:
| ||||||||||||||
providerSettings.providerName | string | Cloud service provider on which Atlas provisioned the hosts. Atlas can return:
| ||||||||||||||
providerSettings.regionName | string | |||||||||||||||
providerSettings.diskIOPS | number | Maximum IOPS the system can perform. | ||||||||||||||
providerSettings.diskTypeName | string | |||||||||||||||
providerSettings.encryptEBSVolume | boolean | Flag that indicates whether the Amazon EBS encryption feature
encrypts the host's root volume for both data at rest within the
volume and for data moving between the volume and the cluster. | ||||||||||||||
providerSettings.instanceSizeName | string | Name of the cluster tier used for the Atlas cluster. Atlas supports the following cluster tiers. Atlas supports deploying M2 and M5 tiers into a subset of available regions. The documentation for providersettings.regionName includes a list of these regions. Note Cluster Tier Naming Conventions Cluster tier names that are:
M2 and M5 clusters are multi-tenant deployments. You must set providerSettings.providerName to TENANT and specify the cloud service provider in providerSettings.backingProviderName. | ||||||||||||||
replicationFactor | number | Number of replica set members. Each member keeps a copy of your databases, providing high availability and data redundancy. For multi-region clusters, add the total number of replicationSpec.<region>.electableNodes to calculate the replication factor of the cluster. If your cluster is a sharded cluster, each shard is a replica set with the specified replication factor. Atlas may return 3, 5, or 7. Tip See also: | ||||||||||||||
replicationSpec | object | Configuration of each region in the cluster. Each element
in this object represents a region where Atlas deploys
your cluster. | ||||||||||||||
replicationSpec.<region> | object | Physical location of the region. The <region> string corresponds to a region where Atlas deploys your cluster. Each <region> object describes the region's priority in elections and the number and type of MongoDB nodes Atlas deploys to the region. | ||||||||||||||
replicationSpec.<region>.analyticsNodes | number | Number of analytics nodes
in the region. Analytics nodes are useful for handling analytic
data such as reporting queries from BI Connector for Atlas. Analytics nodes are
read-only, and can never become the primary. | ||||||||||||||
replicationSpec.<region>.electableNodes | number | Number of electable nodes in the region. Electable nodes
can become the primary and can facilitate local reads. | ||||||||||||||
replicationSpec.<region>.priority | number | Election priority of the region. The highest possible priority is 7, which identifies the Preferred Region of the cluster. Atlas places the primary node in the Preferred Region. The lowest possible priority is 0, which identifies a read-only region. You can have any number of priority 0 read only regions. Priorities 1 through 7 are exclusive: only one region per cluster can be assigned a given priority. | ||||||||||||||
replicationSpec.<region>.readOnlyNodes | number | Number of read-only nodes in the region. Read-only nodes can
never become the primary member, but can facilitate
local reads. | ||||||||||||||
replicationSpecs | array | Configuration for each zone in a
Global Cluster. Each object in this
array represents a zone where Atlas deploys nodes for your
Global Cluster. | ||||||||||||||
replicationSpecs[n].id | string | Unique identifier of the replication object. | ||||||||||||||
replicationSpecs[n].zoneName | string | Name for the zone. | ||||||||||||||
replicationSpecs[n].numShards | number | Number of shards to deploy in the specified zone. | ||||||||||||||
replicationSpecs[n].regionsConfig | object | Physical location of the region. Each regionsConfig object
describes the region's priority in elections and the number and
type of MongoDB nodes that Atlas deploys to the region. | ||||||||||||||
replicationSpecs[n].regionsConfig.<region>.analyticsNodes | number | Number of analytics nodes for Atlas to deploy to the region. Analytics nodes are useful for handling analytic data such as reporting queries from BI Connector for Atlas. Analytics nodes are read-only, and can never become the primary. | ||||||||||||||
replicationSpecs[n].regionsConfig.<region>.electableNodes | number | Number of electable nodes for Atlas to deploy to the region.
Electable nodes can become the primary and can
facilitate local reads. | ||||||||||||||
replicationSpecs[n].regionsConfig.<region>.readOnlyNodes | number | Number of read-only nodes for Atlas to deploy to the region. Read-only nodes can never become the primary, but can facilitate local-reads. Specify 0 if you do not want any read-only nodes in the region. | ||||||||||||||
replicationSpecs[n].regionsConfig.<region>.priority | number | Election priority of the region. If you have regions with only
read-only nodes, set this value to 0. | ||||||||||||||
replicationSpecs[n].zoneName | string | Name for the zone in a Global Cluster. Do not provide
this value if clusterType is not GEOSHARDED. | ||||||||||||||
rootCertType | string | Certificate Authority that MongoDB Atlas clusters use. Value can be
Note Beginning on 1 May 2021, new TLS certificates that MongoDB Atlas creates use ISRG instead of IdenTrust for their root Certificate Authority in line with Let's Encrypt's announcement of this transition. | ||||||||||||||
srvAddress | string | Connection string for
connecting to the Atlas cluster. The +srv modifier
forces the connection to use TLS. The mongoURI parameter
lists additional options. | ||||||||||||||
stateName | string | Current state of the cluster. The possible states are:
| ||||||||||||||
versionReleaseSystem | string | Release cadence that Atlas uses for this cluster. Atlas supports:
