Change subject: IMPALA-12256: Fix DDLs losing create event ids in reloading partitions ...................................................................... Patch Set 6: (1 comment) Sorry I have another question that I forgot to ask in my previous review. I asked this question mostly for my own understanding. Thanks! http://gerrit.cloudera.org:8080/#/c/20145/6/tests/custom_cluster/test_events_custom_configs.py File tests/custom_cluster/test_events_custom_configs.py: http://gerrit.cloudera.org:8080/#/c/20145/6/tests/custom_cluster/test_events_custom_configs.py@858 PS6, Line 858: self.client.execute( : "alter table %s.part drop partition (p=0)" % unique_database) : self.client.execute( : "insert into %s.part partition(p=0) values (1),(2)" % unique_database) : self.client.execute(ddl) I have another question regarding the events corresponding to the 3 queries above. When we submit the 3 queries above to Impala, is it true that the order of the respective events received from HMS is non-deterministic? What if we receive the DROP_PARTITION event prior to the events corresponding to the other 2 queries? Will this DROP_PARTITION event be skipped in this case? Or some logic ensures even in this case (the DROP_PARTITION event arriving first) this DROP_PARTITION will still be skipped? -- To view, visit http://gerrit.cloudera.org:8080/20145 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I052faa093bda69fb16db0d424c1478bba103dad9 Gerrit-Change-Number: 20145 Gerrit-PatchSet: 6 Gerrit-Owner: Quanlong Huang <[email protected]> Gerrit-Reviewer: Fang-Yu Rao <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Quanlong Huang <[email protected]> Gerrit-Reviewer: Sai Hemanth Gantasala <[email protected]> Gerrit-Comment-Date: Sat, 08 Jul 2023 01:29:51 +0000 Gerrit-HasComments: Yes
