Andrei Veprev created CAY-1700:
----------------------------------
Summary: Split long DISJOINT_BY_ID prefetch query on several
smaller queries
Key: CAY-1700
URL: https://issues.apache.org/jira/browse/CAY-1700
Project: Cayenne
Issue Type: Improvement
Components: Core Library
Affects Versions: 3.1M4
Reporter: Andrei Veprev
Fix For: 3.1M4
It is improvement for CAY-1681. From Andrus' comment:
And one more thing we will probably have to implement - breaking down OR query
if it gets too long. This is a real problem which has been repeatedly mentioned
in the context of the paginated queries, and in fact solved in
IncrementalFaultList. see IncrementalFaultList.resolveInterval - it checks the
number of clauses in the qualifier against 'maxFetchSize'. We may need to make
"maxFetchSize" a container property used by IncrementalFaultList as well as our
prefetch strategy, and take it into account in the later.
