chenjunjiedada opened a new pull request #2538: URL: https://github.com/apache/iceberg/pull/2538
This adds a metadata column to indicate whether a row is deleted or not. A delete marker column can be used when finding the deleted rows as we discussed in https://github.com/apache/iceberg/pull/2372, it can also be used to simplify the overall merge on read process. In order to avoid overhead, the delete marker metadata column only projected when the delete files exist. -- This is an automated message from the Apache Git Service.
