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 Change-Id: I9e581ea17fa8f6ccd9c87aaad1281bb694079f6e --- M fe/src/main/java/org/apache/impala/service/IcebergCatalogOpExecutor.java M tests/stress/test_update_stress.py 2 files changed, 119 insertions(+), 7 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/99/20999/1 -- To view, visit http://gerrit.cloudera.org:8080/20999 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: I9e581ea17fa8f6ccd9c87aaad1281bb694079f6e Gerrit-Change-Number: 20999 Gerrit-PatchSet: 1 Gerrit-Owner: Zoltan Borok-Nagy <borokna...@cloudera.com>
