def cancel()

#compression=

def compression=(value)

Sets the compression type. Not applicable when extracting models.

Parameter

• value (String) — The compression type to use for exported files. Possible values include GZIP and NONE. The default value is NONE.

#delimiter=

def delimiter=(value)

Sets the field delimiter. Not applicable when extracting models.

Parameter

• value (String) — Delimiter to use between fields in the exported data. Default is ,.

#format=

def format=(new_format)

Sets the destination file format. The default value for tables is csv. Tables with nested or repeated fields cannot be exported as CSV. The default value for models is ml_tf_saved_model.

Supported values for tables:

• csv - CSV
• json - Newline-delimited JSON
• avro - Avro

Supported values for models:

• ml_tf_saved_model - TensorFlow SavedModel
• ml_xgboost_booster - XGBoost Booster

Parameter

• new_format (String) — The new source format.

#header=

def header=(value)

Print a header row in the exported file. Not applicable when extracting models.

Parameter

• value (Boolean) — Whether to print out a header row in the results. Default is true.

#labels=

def labels=(value)

Sets the labels to use for the job.

Parameter

• value (Hash) —

  A hash of user-provided labels associated with the job. You can use these to organize and group your jobs.

  The labels applied to a resource must meet the following requirements:

  • Each resource can have multiple labels, up to a maximum of 64.
  • Each label must be a key-value pair.
  • Keys have a minimum length of 1 character and a maximum length of 63 characters, and cannot be empty. Values can be empty, and have a maximum length of 63 characters.
  • Keys and values can contain only lowercase letters, numeric characters, underscores, and dashes. All characters must use UTF-8 encoding, and international characters are allowed.
  • The key portion of a label must be unique. However, you can use the same key with multiple resources.
  • Keys must start with a lowercase letter or international character.

def location=(value)

Sets the geographic location where the job should run. Required except for US and EU.

Parameter

• value (String) — A geographic location, such as "US", "EU" or "asia-northeast1". Required except for US and EU.

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new
dataset = bigquery.dataset "my_dataset"
table = dataset.table "my_table"

destination = "gs://my-bucket/file-name.csv"
extract_job = table.extract_job destination do |j|
  j.location = "EU"
end
