[jira] Commented: (DERBY-855) Document optimizer overrides which
were introduced in 10.2
[ http://issues.apache.org/jira/browse/DERBY-855?page=comments#action_12364115 ]
Eric Radzinski commented on DERBY-855:
--------------------------------------
I have a few outstanding questions about documenting this issue:
--I need some help extracting relevant examples from the source that you provided, which is located in: db/derby/code/trunk/java/testing/org/apache/derbyTesting/functionTests/master/optimizerOverrides.out. Which specific ones would be best to use?
--Satheesh mentioned that we need to let the users know that they can see their optimizer overrides in RUNSTAT output. I'm assuming that this update would go in the tuning guide as a separate topic in the "Working with RunTimeStatistics" section. Can you confirm this?
--I need to mention whether the four properties belong after FROM or after table. Can you confirm my understanding of where the four properties can be used: joinOrder can be used with a FROM clause; index, constraint, and joinStrategy can be used only within a TableExpression. Is that correct?
