Query performance slowdown (about 20%) between 1.0.3 and 1.0.4
--------------------------------------------------------------
Key: OJB-91
URL: http://issues.apache.org/jira/browse/OJB-91
Project: OJB
Type: Bug
Versions: 1.0.4
Reporter: Armin Waibel
Assigned to: Armin Waibel
The query performance slowdown in 1.0.4 compared with 1.0.3. It was caused by a
column check in RowReaderImpl. For each row of a result set OJB checks for a
specific column named "OJB_CLAZZ" used to specify the real class name of the
associated object instance when "table per subclass"-inheritance was used.
This check should only happen when "table per subclass"-inheritance was used,
else the jdbc-driver will throw an exception on each object materialization.
