Reduce compilation time for queries with large IN lists made up of literals. ---------------------------------------------------------------------------- Key: DERBY-2483 URL: https://issues.apache.org/jira/browse/DERBY-2483 Project: Derby Issue Type: Improvement Components: Performance Affects Versions: 10.3.0.0 Reporter: A B Priority: Minor Pulled from the write-up of DERBY-47: As seen in the before-and-after.html document attached to DERBY-47, the compilation/optimization time for a query with an IN list consisting of all literals is far larger than it is for a similar in which the IN list consists of all parameters. Since the "probe predicate" optimization implemented as part of DERBY-47 should apply similarly to both types of queries, it would be good to figure out what it is about literals that makes for such a long compilation time (with respect to parameters), and to address that issue. Note that this relatively excessive compilation time was an issue even before the changes for DERBY-47 were committed. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
