[jira] [Created] (BEAM-8393) Java BigQueryIO clustering support
breaks on multiple partitions
Jeff Klukas created BEAM-8393:
---------------------------------
Summary: Java BigQueryIO clustering support breaks on multiple partitions
Key: BEAM-8393
URL: https://issues.apache.org/jira/browse/BEAM-8393
Project: Beam
Issue Type: Bug
Components: io-java-gcp
Affects Versions: 2.15.0, 2.16.0
Reporter: Jeff Klukas
Assignee: Jeff Klukas
Support for writing to clustered tables in BigQuery was added in 2.15, which involved adding a new optional clustering field to TableDestination. Clustering support is working for most cases, but fails with errors about incompatible partitioning specifications for any data that is handled by the MultiplePartitions branch of BigQueryIO logic.
There is a case in that code path where we provide a modified TableDestination and neglect to copy the clustering definition, so the final load job does not include any clustering columns.
