rdblue opened a new pull request #2117: URL: https://github.com/apache/iceberg/pull/2117
This updates how metadata columns are requested for merge plans. Previously, the merge builder automatically added `_file` and `_pos` metadata columns. But but the left anti join case of `MERGE INTO` uses a non-merge scan. To make the metadata columns available in a more reliable way, this adds `withMetadataColumns` to the Iceberg `ScanBuilder`. It also adds `ScanBuilderHelper.asIceberg` to get an Iceberg `ScanBuilder` when needed. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
