apache_beam.io.gcp.bigtableio module

BigTable connector

This module implements writing to BigTable tables. The default mode is to set row data to write to BigTable tables. The syntax supported is described here: https://cloud.google.com/bigtable/docs/quickstart-cbt

BigTable connector can be used as main outputs. A main output (common case) is expected to be massive and will be split into manageable chunks and processed in parallel. In the example below we created a list of rows then passed to the GeneratedDirectRows DoFn to set the Cells and then we call the BigTableWriteFn to insert those generated rows in the table.

main_table = (p
WriteToBigTable(project_id, instance_id, table_id))
class apache_beam.io.gcp.bigtableio.WriteToBigTable(project_id=None, instance_id=None, table_id=None)[source]
