Davide Giannella updated OAK-7390: ---------------------------------- Fix Version/s: 1.14.0 > QueryResult.getSize() can be slow for many "or" or "union" conditions > --------------------------------------------------------------------- > > Key: OAK-7390 > URL: https://issues.apache.org/jira/browse/OAK-7390 > Project: Jackrabbit Oak > Issue Type: Improvement > Components: query > Reporter: Thomas Mueller > Assignee: Thomas Mueller > Priority: Major > Fix For: 1.12.0, 1.14.0 > > > For queries with many union conditions, the "fast" getSize method can > actually be slower than iterating over the result. > The reason is, the number of index calls grows exponential with regards to > number of subqueries: (3x + x^2) / 2, where x is the number of subqueries. > For this to have a measurable affect, the number of subqueries needs to be > large (more than 100), and the index needs to be slow. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
