Thomas Mueller commented on OAK-2679: ------------------------------------- It would make sense also for 1.2 branch (and possibly also 1.0), however there it should not be enabled by default right now, and only enabled if configured. > Query engine: cache execution plans > ----------------------------------- > > Key: OAK-2679 > URL: https://issues.apache.org/jira/browse/OAK-2679 > Project: Jackrabbit Oak > Issue Type: Improvement > Components: core, query > Reporter: Thomas Mueller > Assignee: Thomas Mueller > Labels: performance > Fix For: 1.3.0, 1.2.4 > > Attachments: OAK-2679.patch, executionplancache.patch > > > If there are many indexes, preparing a query can take a long time, in > relation to executing the query. > The query execution plans can be cached. The cache should be invalidated if > there are new indexes, or indexes are changed; a simple solution might be to > use a timeout, and / or a manual cache clean via JMX or so. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
