NAME
    gcloud dataflow jobs drain - drains all jobs that match the command line
        arguments

SYNOPSIS
    gcloud dataflow jobs drain JOB_ID [JOB_ID ...] [--region=REGION_ID]
        [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    Once Drain is triggered, the pipeline will stop accepting new inputs. The
    input watermark will be advanced to infinity. Elements already in the
    pipeline will continue to be processed. Drained jobs can safely be
    cancelled.

POSITIONAL ARGUMENTS
     JOB_ID [JOB_ID ...]
        Job IDs to operate on.

FLAGS
     --region=REGION_ID
        Region ID of the jobs' regional endpoint. Defaults to 'us-central1'.

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.
