Thomas Mueller created OAK-1999:
-----------------------------------
Summary: Query engine is slow when using many "or" constraints
Key: OAK-1999
URL: https://issues.apache.org/jira/browse/OAK-1999
Project: Jackrabbit Oak
Issue Type: Improvement
Components: query
Reporter: Thomas Mueller
Assignee: Thomas Mueller
For queries with many (300 or so) "or" constraints of the form "x = 1 or x = 2
or x = 3", the query engine uses quite a lot of CPU time. According to
profiling data, this is due to using "toString()" too often, and "Sets.union"
(com.google.common.collect.Sets).
The Oak 1.0 branch is affected most, not sure about trunk.
