Enable optimizer trace in Derby
-------------------------------
Key: DERBY-837
URL: http://issues.apache.org/jira/browse/DERBY-837
Project: Derby
Type: New Feature
Versions: 10.2.0.0
Reporter: Mamta A. Satoor
Derby engine has code to produce trace for optimization phase ie various plans
considered by the optimizer for a query. This trace however does not get
produced because there is no way to turn the trace on. When someone does work
on providing a way to enable the optimizer trace, we will also need to decide
in what format this trace should be presented. Further information on this
issue can be found at
