# The ClusterPolicyRevision object

Represents a cluster policy revision.

 Only the 100 most recent revisions are stored for each cluster policy.

## Attributes

- `revision_id` (string)
  ID of the cluster policy revision.
- `create_time` (string)
  Time when the cluster policy revision was created.
- `settings` (object)
  Settings used to create/edit the policy.
  - `name` (string)
    Cluster Policy name requested by the user. This has to be unique. Length must be between 1 and 100
     characters.
  - `definition` (string)
    Policy definition document expressed in [Databricks Cluster Policy Definition Language](https://docs.databricks.com/administration-guide/clusters/policy-definition.html).
  - `description` (string)
    Additional human-readable description of the cluster policy.
    Constraints: `<= 1000 characters`
  - `policy_family_id` (string)
    ID of the policy family. The cluster policy's policy definition inherits the policy
     family's policy definition.
    
     Cannot be used with `definition`. Use `policy_family_definition_overrides` instead to
     customize the policy definition.
  - `policy_family_definition_overrides` (string)
    Policy definition JSON document expressed in [Databricks Policy Definition Language](https://docs.databricks.com/administration-guide/clusters/policy-definition.html).
     The JSON document must be passed as a string and cannot be embedded in the requests.
    
     You can use this to customize the policy definition inherited from the policy family.
     Policy rules specified here are merged into the inherited policy definition.
  - `max_clusters_per_user` (int64)
    Max number of clusters per user that can be active using this policy. If not present, there is no max limit.
    Constraints: `>= 1`
  - `libraries` (array of object)
    A list of libraries to be installed on the next cluster restart that uses this policy. The maximum number of libraries is 500.
    - `jar` (string)
      URI of the JAR library to install. Supported URIs include Workspace paths, Unity Catalog Volumes paths, and S3 URIs.
       For example: `{ "jar": "/Workspace/path/to/library.jar" }`, `{ "jar" : "/Volumes/path/to/library.jar" }` or
       `{ "jar": "s3://my-bucket/library.jar" }`.
       If S3 is used, please make sure the cluster has read access on the library. You may need to
       launch the cluster with an IAM role to access the S3 URI.

      For example: `{ "jar": "/Workspace/path/to/library.jar" }`, `{ "jar" : "/Volumes/path/to/library.jar" }` or
      `{ "jar": "abfss://my-bucket/library.jar" }`.
      If ADLS is used, please make sure the cluster has read access on the library. You may need to
      launch the cluster with a Microsoft Entra ID service principal to access the ADLS URI.
      **GCP:** URI of the jar library to be installed. Supported URIs include Workspace path, UC Volumes path, and GCS URIs.
      For example: `{ "jar": "/Workspace/path/to/library.jar" }`, `{ "jar" : "/Volumes/path/to/library.jar" }` or
      `{ "jar": "gs://my-bucket/library.jar" }`.
      If GCS is used, please make sure the cluster has read access on the library. You may need to
      launch the cluster with an IAM service account to access the GCS URI.
