------------------------------------------
Assignee: Zoltán Borók-Nagy
> Concurrent DELETE and UPDATE operations on Iceberg tables can be problematic
> ----------------------------------------------------------------------------

> Key: IMPALA-12787
> URL: https://issues.apache.org/jira/browse/IMPALA-12787
> Project: IMPALA
> Issue Type: Bug
> Components: Catalog
> Reporter: Zoltán Borók-Nagy
> Assignee: Zoltán Borók-Nagy
> Priority: Major
> Labels: impala-iceberg
>
> If an UPDATE operation runs concurrently with a DELETE operation, and the
> DELETE commits first, then the UPDATE can revive deleted rows.
> This is because only RowDelta.validateNoConflictingDataFiles() is called, but
> RowDelta.validateNoConflictingDeleteFiles() is not. Therefore, the UPDATE
> operation ignores the concurrently written delete files.
