NAME
    gcloud alpha metastore federations create - create a Dataproc Metastore
        federation

SYNOPSIS
    gcloud alpha metastore federations create
        (FEDERATION : --location=LOCATION) --backends=RANK=BACKEND [--async]
        [--hive-metastore-version=HIVE_METASTORE_VERSION]
        [--labels=[KEY=VALUE,...]] [--tags=[KEY=VALUE,...]]
        [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    (ALPHA) Create a new Dataproc Metastore federation with the given name and
    configurations.

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

        gcloud metastore operations describe

EXAMPLES
    To create a Dataproc Metastore federation with the name
    my-metastore-federation in location us-central with two backends dpms1 and
    dpms2, run:

        $ gcloud alpha metastore federations create \
          my-metastore-federation --location=us-central1 \
          --backends=1=dpms:dpms1,2=dpms:projects/my-project/locations/\
        us-central1/services/dpms2

POSITIONAL ARGUMENTS
     Federation resource - Arguments and flags that specify the Dataproc
     Metastore federation you want to create. The arguments in this group can
     be used to specify the attributes of this resource. (NOTE) Some attributes
     are not given arguments in this group but can be set in other ways.

     To set the project attribute:
      ◆ provide the argument federation on the command line with a fully
        specified name;
      ◆ provide the argument --project on the command line;
      ◆ set the property core/project.

     This must be specified.

       FEDERATION
          ID of the federation or fully qualified identifier for the
          federation.

          To set the federation attribute:
          ▸ provide the argument federation on the command line.

          This positional argument must be specified if any of the other
          arguments in this group are specified.

       --location=LOCATION
          The location of the Dataproc Metastore service.

          If not specified, will use default metastore/location.

          To set the location attribute:
          ▸ provide the argument federation on the command line with a fully
            specified name;
          ▸ provide the argument --location on the command line;
          ▸ set the property metastore/location.

REQUIRED FLAGS
     --backends=RANK=BACKEND
        Backends from which the federation service serves metadata at query
        time. The backends are specified as a comma-separated list of
        RANK=BACKEND pairs. For example:
        1=dpms:dpms1,2=dpms:projects/my-project/locations/us-central1/services/dpms2.
        RANK represents the rank of the backend metastore and is used to
        resolve database name collisions. BACKEND is specified as
        METASTORE_TYPE:METASTORE_NAME where METASTORE_TYPE is the type of
        backend metastore and METASTORE_NAME is the relative resource name of
        the metastore. If only the name of the metastore is specified (e.g.
        dpms1), project and location will be inferred from the project and
        location used to create the federation.

OPTIONAL FLAGS
     --async
        Return immediately, without waiting for the operation in progress to
        complete.

     --hive-metastore-version=HIVE_METASTORE_VERSION
        Hive metastore schema version of the Metastore federation.
        HIVE_METASTORE_VERSION must be one of: 2.3.6, 3.1.2.

     --labels=[KEY=VALUE,...]
        List of label KEY=VALUE pairs to add.

        Keys must start with a lowercase character and contain only hyphens
        (-), underscores (_), lowercase characters, and numbers. Values must
        contain only hyphens (-), underscores (_), lowercase characters, and
        numbers.

     --tags=[KEY=VALUE,...]
        List of tag KEY=VALUE pairs to add.

GCLOUD WIDE FLAGS
    These flags are available to all commands: --access-token-file, --account,
    --billing-project, --configuration, --flags-file, --flatten, --format,
    --help, --impersonate-service-account, --log-http, --project, --quiet,
    --trace-token, --user-output-enabled, --verbosity.

    Run $ gcloud help for details.

API REFERENCE
    This command uses the metastore/v1alpha API. The full documentation for
    this API can be found at: https://cloud.google.com/dataproc-metastore/docs

NOTES
    This command is currently in alpha and might change without notice. If this
    command fails with API permission errors despite specifying the correct
    project, you might be trying to access an API with an invitation-only early
    access allowlist. These variants are also available:

        $ gcloud metastore federations create

        $ gcloud beta metastore federations create
