NAME
    gcloud firestore indexes fields update - update the index configuration of
        the given field

SYNOPSIS
    gcloud firestore indexes fields update
        (FIELD : --collection-group=COLLECTION_GROUP)
        (--clear-exemption | --disable-indexes
          | --index=[array-config=ARRAY-CONFIG],[order=ORDER]) [--async]
        [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    Update the index configuration of the given field.

    This creates an exemption for the field in question, allowing one to modify
    the field's index settings and override the defaults.

EXAMPLES
    The following command creates an exemption for the timestamp field in the
    Events collection group, in which all indexes are disabled:

        $ gcloud firestore indexes fields update timestamp \
            --collection-group=Events --disable-indexes

    The following command creates an exemption for the timestamp field in the
    Events collection group, in which the list of indexes is explicitly set to
    [ASCENDING, DESCENDING]:

        $ gcloud firestore indexes fields update timestamp \
            --collection-group=Events --index=order=ASCENDING \
            --index=order=DESCENDING

    The following command clears the exemption on the timestamp field in the
    Events collection group, so that the field will return to inheriting its
    index settings from its ancestors:

        $ gcloud firestore indexes fields update timestamp \
            --collection-group=Events --clear-exemption

POSITIONAL ARGUMENTS
     Field resource - Field 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 field on the command line with a fully specified
        name;
      ◆ set the property core/project;
      ◆ provide the argument --project on the command line. To set the
        database attribute:
      ◆ provide the argument field on the command line with a fully specified
        name;
      ◆ provide the argument [--database] on the command line (currently
        '(default)' is the only supported value).

     This must be specified.

       FIELD
          ID of the field or fully qualified identifier for the field. To set
          the field attribute:
          ▸ provide the argument field on the command line.

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

       --collection-group=COLLECTION_GROUP
          Collection group of the field.

          To set the collection-group attribute:
          ▸ provide the argument field on the command line with a fully
            specified name;
          ▸ provide the argument --collection-group on the command line.

REQUIRED FLAGS
     Exactly one of these must be specified:

       --clear-exemption
          If provided, the field's current index configuration will be reverted
          to inherit from its ancestor index configurations.

       --disable-indexes
          If provided, the field will no longer be indexed at all.

       --index=[array-config=ARRAY-CONFIG],[order=ORDER]
          An index for the field.

          This flag can be repeated to provide multiple indexes. Any existing
          indexes will be overwritten with the ones provided. Any omitted
          indexes will be deleted if they currently exist.

          The following keys are allowed:

           order
              Specifies the order. Valid options are: 'ascending',
              'descending'. Exactly one of 'order' or 'array-config' must be
              specified.

           array-config
              Specifies the configuration for an array field. The only valid
              option is 'contains'. Exactly one of 'order' or 'array-config'
              must be specified.

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

GCLOUD WIDE FLAGS
