Rick Hillegas created DERBY-6259:
------------------------------------
Summary: Collapse the level 2 optimizer into its parent module.
Key: DERBY-6259
URL: https://issues.apache.org/jira/browse/DERBY-6259
Project: Derby
Issue Type: Improvement
Components: SQL
Affects Versions: 10.11.0.0
Reporter: Rick Hillegas
Right now there are 2 optimizer implementations, only one of which is ever
loaded. The other implementation was disabled by the following comment in
modules.properties:
# use level1 optimizer for small configurations
#
# can't do this in the codeline because with 2 implementations, it is entirely
# by chance which get picked. So we may be running with different modules
# depending on which jdk
#
# to be resolve by Siuling and Dan
#
#derby.module.optimizerSmall=org.apache.derby.impl.sql.compile.OptimizerFactoryImpl
#cloudscape.config.optimizerSmall=cloud,cloudtarget
Since we have deprecated support for the small CDC configuration, I don't think
that we need further resolution by Siuling and Dan. Collapsing the two
optimizers together should slightly reduce our static footprint.
