########## format/spec.md: ########## @@ -1416,6 +1417,8 @@ The rows in the delete file must be sorted by `file_path` then `pos` to optimize Equality delete files identify deleted rows in a collection of data files by one or more column values, and may optionally contain additional columns of the deleted row. +Equality deletes are not an allowed entry type in v4 metadata, so new equality deletes must not be written to v4 tables. Equality deletes carried over from v2 or v3 remain in the delete manifests that already track them and must still be applied when reading. Converting them to [deletion vectors](#deletion-vectors) is a separate, optional maintenance action. Review Comment: Thanks, addressed. Both sites now use the same wording as the Delete Formats sentence: `Equality delete files must not be added to v4 tables`. -- This is an automated message from the Apache Git Service.
