terraform-google-bigquery

This module allows you to create opinionated Google Cloud Platform BigQuery datasets and tables. This will allow the user to programmatically create an empty table schema inside of a dataset, ready for loading. Additional user accounts and permissions are necessary to begin querying the newly created table(s).

Compatibility

This module is meant for use with Terraform 0.12. If you haven't upgraded and need a Terraform 0.11.x-compatible version of this module, the last released version intended for Terraform 0.11.x is 1.0.0.

Upgrading

The current version is 4.X. The following guides are available to assist with upgrades:

• 3.0 -> 4.0
• 2.0 -> 3.0
• 1.0 -> 2.0
• 0.1 -> 1.0

Usage

Basic usage of this module is as follows:

module "bigquery" {
  source  = "terraform-google-modules/bigquery/google"
  version = "~> 4.3"

  dataset_id                  = "foo"
  dataset_name                = "foo"
  description                 = "some description"
  project_id                  = "<PROJECT ID>"
  location                    = "US"
  default_table_expiration_ms = 3600000

  tables = [
  {
    table_id          = "foo",
    schema            =  "<PATH TO THE SCHEMA JSON FILE>",
    time_partitioning = {
      type                     = "DAY",
      field                    = null,
      require_partition_filter = false,
      expiration_ms            = null,
    },
    expiration_time = null,
    clustering      = ["fullVisitorId", "visitId"],
    labels          = {
      env      = "dev"
      billable = "true"
      owner    = "joedoe"
    },
  },
  {
    table_id          = "bar",
    schema            =  "<PATH TO THE SCHEMA JSON FILE>",
    time_partitioning = null,
    expiration_time   = 2524604400000, # 2050/01/01
    clustering        = [],
    labels = {
      env      = "devops"
      billable = "true"
      owner    = "joedoe"
    },
  }
  ],

  views = [
    {
      view_id    = "barview",
      use_legacy_sql = false,
      query          = <<EOF
      SELECT
       column_a,
       column_b,
      FROM
        `project_id.dataset_id.table_id`
      WHERE
        approved_user = SESSION_USER
      EOF,
      labels = {
        env      = "devops"
        billable = "true"
        owner    = "joedoe"
      }
    }
  ]
  dataset_labels = {
    env      = "dev"
    billable = "true"
  }
}

Variable tables detailed description

The tables variable should be provided as a list of object with the following keys:

{
  table_id = "some_id"                        # Unique table id (will be used as ID and Freandly name for the table).
  schema = "path/to/schema.json"              # Path to the schema json file.
  time_partitioning = {                       # Set it to `null` to omit partitioning configuration for the table.
        type                     = "DAY",     # The only type supported is DAY, which will generate one partition per day based on data loading time.
        field                    = null,      # The field used to determine how to create a time-based partition. If time-based partitioning is enabled without this value, the table is partitioned based on the load time. Set it to `null` to omit configuration.
        require_partition_filter = false,     # If set to true, queries over this table require a partition filter that can be used for partition elimination to be specified. Set it to `null` to omit configuration.
        expiration_ms            = null,      # Number of milliseconds for which to keep the storage for a partition.
      },
  clustering = ["fullVisitorId", "visitId"]   # Specifies column names to use for data clustering. Up to four top-level columns are allowed, and should be specified in descending priority order. Partitioning should be configured in order to use clustering.
  expiration_time = 2524604400000             # The time when this table expires, in milliseconds since the epoch. If set to `null`, the table will persist indefinitely.
  labels = {                                  # A mapping of labels to assign to the table.
      env      = "dev"
      billable = "true"
    }
}

Variable views detailed description

The views variable should be provided as a list of object with the following keys:

{
  view_id = "some_id"                                                # Unique view id. it will be set to friendly name as well
  query = "Select user_id, name from `project_id.dataset_id.table`"  # the Select query that will create the view. Tables should be created before.
  use_legacy_sql = false                                             # whether to use legacy sql or standard sql
  labels = {                                                         # A mapping of labels to assign to the view.
      env      = "dev"
      billable = "true"
  }
}
