Change subject: IMPALA-13850 (part 1): Wait until CatalogD active before resetting ...................................................................... Patch Set 16: (1 comment) http://gerrit.cloudera.org:8080/#/c/22634/15//COMMIT_MSG Commit Message: http://gerrit.cloudera.org:8080/#/c/22634/15//COMMIT_MSG@24 PS15, Line 24: : The later prerequisite is to ensure that all coordinators are not : blocked waiting for full topic update in on-demand metadata mode. This : is all manage > Is this an option for you? https://gerrit.cloudera.org/c/22634/7//COMMIT_MS I am hesitant to introduce new concept (IncompleteDb) for legacy catalog mode just for this purpose when it is due for deprecation. I think it is best to keep Coordinator continue serving queries rather than making queries wait or fail until full catalog topic is received. One scenario I think of is a situation where 2 CatalogD keep bouncing active-standby status between them. I will be a bad experience if Coordinator stop serving all kind of queries in that scenario. Some read-only queries over stable tables (unchanged metadata) should be eligible to run while CatalogD failover is happening. Patch set 16 restore the need for initial reset metadata for legacy catalog mode. -- To view, visit http://gerrit.cloudera.org:8080/22634 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I58cc66dcccedb306ff11893f2916ee5ee6a3efc1 Gerrit-Change-Number: 22634 Gerrit-PatchSet: 16 Gerrit-Owner: Riza Suminto <riza.sumi...@cloudera.com> Gerrit-Reviewer: Abhishek Rawat <ara...@cloudera.com> Gerrit-Reviewer: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Gerrit-Reviewer: Quanlong Huang <huangquanl...@gmail.com> Gerrit-Reviewer: Riza Suminto <riza.sumi...@cloudera.com> Gerrit-Reviewer: Wenzhe Zhou <wz...@cloudera.com> Gerrit-Comment-Date: Mon, 14 Apr 2025 19:47:02 +0000 Gerrit-HasComments: Yes
