Change subject: IMPALA-14832: Make auto-incrementing Kudu columns hidden and simplify code ...................................................................... Patch Set 4: > auto-incrementing columns in kudu tables are half-hidden. They are not shown > in 'select *', but could be explicitly selected as auto_incrementing_id. > Agree to show the column in DESCRIBE EXTENDED output. +1 The reason for this behavior is to allow users to access this column data, if needed. (for example when trying to identify a row which can only be done by the entire primary key column set). Exposing it in DESCRIBE/DESCRIBE EXTENDED output is to allow the end user to confirm the column exists. > omitting it during CREATE TABLE LIKE This could mean the new table would have unique key columns then? AFAIK Impala doesn't create the auto_incrementing_id column explicitly during CREATE TABLE LIKE (as Kudu blocks it). It only declares the primary key columns are non-unique and Kudu will create this column internally. -- To view, visit http://gerrit.cloudera.org:8080/24097 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I5da031c5dcd93ed02a6f9a21006325c2077be1e9 Gerrit-Change-Number: 24097 Gerrit-PatchSet: 4 Gerrit-Owner: Zoltan Borok-Nagy <[email protected]> Gerrit-Reviewer: Abhishek Chennaka <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Michael Smith <[email protected]> Gerrit-Reviewer: Wenzhe Zhou <[email protected]> Gerrit-Reviewer: Zoltan Borok-Nagy <[email protected]> Gerrit-Comment-Date: Wed, 25 Mar 2026 19:29:23 +0000 Gerrit-HasComments: No
