create a snapshot of a BigQuery table

Demonstrates creating a snapshot table from a managed BigQuery table.

Code sample

Python

Before trying this sample, follow the Python setup instructions in the BigQuery quickstart using client libraries. For more information, see the BigQuery Python API reference documentation.

To authenticate to BigQuery, set up Application Default Credentials. For more information, see Set up authentication for client libraries.

from google.cloud import bigquery

# TODO(developer): Set table_id to the ID of the table to create.
source_table_id = "your-project.your_dataset.your_table_name"
snapshot_table_id = "your-project.your_dataset.snapshot_table_name"

# Construct a BigQuery client object.
client = bigquery.Client()
copy_config = bigquery.CopyJobConfig()
copy_config.operation_type = bigquery.OperationType.SNAPSHOT

copy_job = client.copy_table(
    sources=source_table_id,
    destination=snapshot_table_id,
    job_config=copy_config,
)
copy_job.result()

print("Created table snapshot {}".format(snapshot_table_id))
