Description

We would like to have an equivalent of withNumFileShards() in Python as well

.apply("WriteInBigQueryLoad", BigQueryIO.writeTableRows().to(tableLowUrgency)
.withSchema(schema)
.withMethod(Method.FILE_LOADS)
.withTriggeringFrequency(Duration.standardMinutes(2))
.withNumFileShards(1)
.withCreateDisposition(BigQueryIO.Write.CreateDisposition.CREATE_IF_NEEDED)
.withWriteDisposition(BigQueryIO.Write.WriteDisposition.WRITE_APPEND))

transformed | 'Write' >> beam.io.WriteToBigQuery(
known_args.target_table,
schema=schema,
create_disposition=beam.io.BigQueryDisposition.CREATE_IF_NEEDED,
write_disposition=beam.io.BigQueryDisposition.WRITE_APPEND,
method=beam.io.WriteToBigQuery.Method.FILE_LOADS,
triggering_frequency=5
)
