Hello Tamas Mate, Impala Public Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/20999
to look at the new patch set (#2).
Change subject: IMPALA-12787: Concurrent DELETE and UPDATE operations on
Iceberg tables can be problematic
......................................................................
IMPALA-12787: Concurrent DELETE and UPDATE operations on Iceberg tables can be
problematic
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.
This patch adds RowDelta.validateNoConflictingDeleteFiles() to UPDATE
operations.
Testing
* added a stress test to validate concurrent DELETE and UPDATE
operations
