    brief: Update an existing Bigtable schema bundle.
    description: Update an existing Bigtable schema bundle.
    examples: |
      To update a schema bundle `my-schema-bundle` in instance `my-instance` and table
      `my-table`, using the descriptor file `my-descriptor-file.pb`:

        $ {command} my-schema-bundle --instance=my-instance --table=my-table --proto-descriptors-file=my-descriptor-file.pb

    collection: bigtableadmin.projects.instances.tables.schemaBundles

      help_text: Bigtable schema bundle to update.
      spec: !REF googlecloudsdk.command_lib.bigtable.resources:schema_bundle

      help_text: |
            Path of a file that contains a protobuf-serialized `google.protobuf.FileDescriptorSet` message. If specified, the schema bundle contains the protobuf schema.
            To generate the file, install and run `protoc` with the following command:

              protoc --proto_path=IMPORT_PATH --include_imports --descriptor_set_out=DESCRIPTOR_OUTPUT_LOCATION path/to/file.proto

            where the --proto_path option specificies where to look for .proto files when resolving import directives (the current directory is used if you do not provide a value),
            and the --descriptor_set_out option specifies where you want the generated FileDescriptorSet to be written.
