Search before asking

  • I searched in the issues and found nothing similar.

Motivation

Currently, partial update in paimon only supports mor and generates a completed changelog during full compaction. We hope that partial update will support the cow mode to directly generate complete data of columns during writing, so that downstream jobs can read the complete updated results immediately

Solution
