> If I understood correctly autoSharding uses GroupIntoBatches.withShardedKey. It is only supported in Dataflow runner v2. Under runner v1 this flag would cause error. Context: #26416 switching the default would break runner v1 user The autoSharing default change in this PR only impacts how data is written into BigQuery table in the BigQueryIO.Write client when STORAGE_WRITE_API is used as method. When STORAGE_WRITE_API is used, autoSharding needs to be enabled by default. Also, this change only impact SchemaIO transforms used in Syndeo templates. -- This is an automated message from the Apache Git Service.
