Todd Lipcon created KUDU-3032: --------------------------------- Summary: key columns unnecessarily selected when predicate is converted to range Key: KUDU-3032 URL: https://issues.apache.org/jira/browse/KUDU-3032 Project: Kudu Issue Type: Bug Components: perf Affects Versions: 1.11.1 Reporter: Todd Lipcon
When a predicate applies to leading primary key columns, the tablet service optimizes it into a range scan and removes those predicates from the ScanSpec. However, the current behavior (seemingly going back to when this was implemented) does not actually prevent those key columns from being read from disk. This has a negative performance impact, particularly when the keys are large or inefficient to decompress. -- This message was sent by Atlassian Jira (v8.3.4#803005)
