[jira] Created: (CAY-1548) PkQuery - a query to reserve a PK for a
given object before commit.
PkQuery - a query to reserve a PK for a given object before commit.
-------------------------------------------------------------------
Key: CAY-1548
URL: https://issues.apache.org/jira/browse/CAY-1548
Project: Cayenne
Issue Type: Sub-task
Reporter: Andrus Adamchik
Assignee: Andrus Adamchik
Priority: Minor
Will create a new query - PkQuery, that will be used to reserve a PK for a given object before commit. It should return a List<Long> with a single PK. Not sure if there is a point in batching it (fetch multiple PKs in one shot?) Won't do batching initially.

--------------------------------------------------------------
This approach appears to be a dead end. In particular PkQuery can not be combined with entities with "generated" PK, as "generated" PK bypasses Cayenne PkGenerator. Still attaching a working PkQuery patch with a single simple test. Maybe somebody finds it useful.
