      Alter metadata table properties.
    description: |
      Alter metadata table properties from a Dataproc Metastore service's underlying metadata store.

      If run asynchronously with `--async`, exits after printing
      one operation name that can be used to poll the status of the
      creation via:

        {top_command} metastore operations describe
    examples: |
      To alter metadata table properties a and b on table-name
      `databases/{database_id}/tables/{table_id}`
      , use the update-mask `properties.a,properties.b`
      , and run:

          $ {command} my-metastore-service --location=us-central1
            --table-name=databases/my-database/tables/my-table
            --update-mask=properties.a,properties.b
            --properties=a=1,b=2

      required: true
    - arg_name: update-mask
      api_field: alterTablePropertiesRequest.updateMask
      help_text: |
        A string where field names are separated by a comma. Specifies the metadata table properties
         fields that are overwritten by the update. Fields specified in the `update-mask` are
          relative to the resource (not to the full request). A field is overwritten if it is in
          the mask.

        For example, given the target properties:

            properties {
              a: 1
              b: 2
            }

        And an update properties:

            properties {
              a: 2
              b: 3
              c: 4
            }

        then if the field mask is:

        `properties.b,properties.c`

        then the updated result will be:

            properties {
              a: 1
              b: 3
              c: 4
            }
      required: true
    - arg_name: properties
      api_field: alterTablePropertiesRequest.properties.additionalProperties
      help_text: |
         A string where field names are separated by a comma. Describes the desired values to mutate.
         If update-mask is empty, the properties will not update. Otherwise, the properties only
         alter the values whose associated paths exist in the update mask.

         For example, the desired key-value pairs.

         a=2,b=3,c=4
