» google_dataflow_job

Creates a job on Dataflow, which is an implementation of Apache Beam running on Google Compute Engine. For more information see the official documentation for Beam and Dataflow.

» Example Usage

resource "google_dataflow_job" "big_data_job" {
    name = "dataflow-job"
    template_gcs_path = "gs://my-bucket/templates/template_file"
    temp_gcs_location = "gs://my-bucket/tmp_dir"
    parameters = {
        foo = "bar"
        baz = "qux"

» Note on "destroy" / "apply"

There are many types of Dataflow jobs. Some Dataflow jobs run constantly, getting new data from (e.g.) a GCS bucket, and outputting data continuously. Some jobs process a set amount of data then terminate. All jobs can fail while running due to programming errors or other issues. In this way, Dataflow jobs are different from most other Terraform / Google resources.

The Dataflow resource is considered 'existing' while it is in a nonterminal state. If it reaches a terminal state (e.g. 'FAILED', 'COMPLETE', 'CANCELLED'), it will be recreated on the next 'apply'. This is as expected for jobs which run continously, but may surprise users who use this resource for other kinds of Dataflow jobs.

A Dataflow job which is 'destroyed' may be "cancelled" or "drained". If "cancelled", the job terminates - any data written remains where it is, but no new data will be processed. If "drained", no new data will enter the pipeline, but any data currently in the pipeline will finish being processed. The default is "cancelled", but if a user sets on_delete to "drain" in the configuration, you may experience a long wait for your terraform destroy to complete.

» Argument Reference

The following arguments are supported:

  • name - (Required) A unique name for the resource, required by Dataflow.
  • template_gcs_path - (Required) The GCS path to the Dataflow job template.
  • temp_gcs_location - (Required) A writeable location on GCS for the Dataflow job to dump its temporary data.

  • parameters - (Optional) Key/Value pairs to be passed to the Dataflow job (as used in the template).
  • max_workers - (Optional) The number of workers permitted to work on the job. More workers may improve processing speed at additional cost.
  • on_delete - (Optional) One of "drain" or "cancel". Specifies behavior of deletion during terraform destroy. See above note.
  • project - (Optional) The project in which the resource belongs. If it is not provided, the provider project is used.
  • zone - (Optional) The zone in which the created job should run. If it is not provided, the provider zone is used.
  • service_account_email - (Optional) The Service Account email used to create the job.
  • network - (Optional) The network to which VMs will be assigned. If it is not provided, "default" will be used.
  • subnetwork - (Optional) The subnetwork to which VMs will be assigned. Should be of the form "regions/REGION/subnetworks/SUBNETWORK".
