POST /api/atlas/v2/groups/{groupId}/flexClusters:tenantUpgrade
Service accounts Digest auth

Upgrades a flex cluster to a dedicated cluster (M10+) in the specified project. To use this resource, the requesting Service Account or API Key must have the Project Cluster Manager role.

Path parameters

  • groupId string Required

    Unique 24-hexadecimal digit string that identifies your project. Use the /groups endpoint to retrieve all projects to which the authenticated user has access.

    NOTE: 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.

    Format should match the following pattern: ^([a-f0-9]{24})$.

Query parameters

  • envelope boolean

    Flag that indicates whether Application wraps the response in an envelope JSON object. Some API clients cannot access the HTTP response headers or status code. To remediate this, set envelope=true in the query. Endpoints that return a list of results use the results object as an envelope. Application adds the status parameter to the response body.

    Default value is false.

  • pretty boolean

    Flag that indicates whether the response body should be in the prettyprint format.

    Default value is false.

  • acceptDataRisksAndForceReplicaSetReconfig string(date-time)

    If reconfiguration is necessary to regain a primary due to a regional outage, submit this field alongside your topology reconfiguration to request a new regional outage resistant topology. Forced reconfigurations during an outage of the majority of electable nodes carry a risk of data loss if replicated writes (even majority committed writes) have not been replicated to the new primary node. MongoDB Atlas docs contain more information. To proceed with an operation which carries that risk, set acceptDataRisksAndForceReplicaSetReconfig to the current date. This parameter expresses its value in the ISO 8601 timestamp format in UTC.

  • redactClientLogData boolean

    Enable or disable log redaction.

    This setting configures the mongod or mongos to redact any document field contents from a message accompanying a given log event before logging. This prevents the program from writing potentially sensitive data stored on the database to the diagnostic log. Metadata such as error or operation codes, line numbers, and source file names are still visible in the logs.

    Use redactClientLogData in conjunction with Encryption at Rest and TLS/SSL (Transport Encryption) to assist compliance with regulatory requirements.

    Note: changing this setting on a cluster will trigger a rolling restart as soon as the cluster is updated.

    Log Redaction
  • replicaSetScalingStrategy string

    Set this field to configure the replica set scaling mode for your cluster.

    By default, Atlas scales under WORKLOAD_TYPE. This mode allows Atlas to scale your analytics nodes in parallel to your operational nodes.

    When configured as SEQUENTIAL, Atlas scales all nodes sequentially. This mode is intended for steady-state workloads and applications performing latency-sensitive secondary reads.

    When configured as NODE_TYPE, Atlas scales your electable nodes in parallel with your read-only and analytics nodes. This mode is intended for large, dynamic workloads requiring frequent and timely cluster tier scaling. This is the fastest scaling strategy, but it might impact latency of workloads when performing extensive secondary reads.

    Values are SEQUENTIAL, WORKLOAD_TYPE, or NODE_TYPE. Default value is WORKLOAD_TYPE.

  • replicationSpecs array[object]

    Hide replicationSpecs attributes Show replicationSpecs attributes object
    • regionConfigs array[object]

      Hardware specifications for nodes set for a given region. Each regionConfigs object must be unique by region and cloud provider within the replicationSpec.

Each regionConfigs object must have either an analyticsSpecs object, electableSpecs object, or readOnlySpecs object. Tenant clusters only require electableSpecs. Dedicated clusters can specify any of these specifications, but must have at least one electableSpecs object within a replicationSpec.

      Example:

      If you set replicationSpecs[n].regionConfigs[m].analyticsSpecs.instanceSize : M30, set replicationSpecs[n].regionConfigs[m].electableSpecs.instanceSize : M30 if you have electable nodes and replicationSpecs[n].regionConfigs[m].readOnlySpecs.instanceSize : M30 if you have read-only nodes.
