NAME
    gcloud beta metastore federations update - update a Dataproc Metastore
        federation

SYNOPSIS
    gcloud beta metastore federations update (FEDERATION : --location=LOCATION)
        (--update-backends=RANK=BACKEND --clear-backends
          | --remove-backends=RANK) [--async] [--update-labels=[KEY=VALUE,...]]
        [--clear-labels | --remove-labels=[KEY,...]] [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    (BETA) Update the metadata and/or configuration parameters of a Dataproc
    Metastore federation.

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

        gcloud metastore operations describe

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

        $ gcloud beta metastore federations update my-metastore-federation \
          --location=us-central1 \
          --update-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 update. 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
     Update the backend metastores by passing key-value pairs in through the
     flags.

     At least one of these must be specified:

       --update-backends=RANK=BACKEND
          Comma-separated list of metastore backends specified as a 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.

       At most one of these can be specified:

         --clear-backends
            Clear existing metastore backends. --clear-backends must be used
            with --update-backends.

         --remove-backends=RANK
            Comma-separated list of metastore backend keys to remove with the
            form RANK1,RANK2. The Key represents the rank of the backend
            metastore and is used to resolve database name collisions. If a
            RANK does not exist then it is sliently ignored. If
            --update-backends is also specified, then --remove-backends is
            applied first.

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

     --update-labels=[KEY=VALUE,...]
        List of label KEY=VALUE pairs to update. If a label exists, its value
        is modified. Otherwise, a new label is created.

        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.

     At most one of these can be specified:

       --clear-labels
          Remove all labels. If --update-labels is also specified then
          --clear-labels is applied first.

          For example, to remove all labels:

              $ gcloud beta metastore federations update --clear-labels

          To remove all existing labels and create two new labels, foo and baz:

              $ gcloud beta metastore federations update --clear-labels \
                --update-labels foo=bar,baz=qux

       --remove-labels=[KEY,...]
          List of label keys to remove. If a label does not exist it is
          silently ignored. If --update-labels is also specified then
          --update-labels is applied first.

GCLOUD WIDE FLAGS
    These flags are available to all commands: --access-token-file, --account,
    --billing-project, --configuration, --flags-file, --flatten, --format,
