Subject [jira] Commented: (DERBY-3313) JDBC client driver statement cache
Date Thu, 17 Jan 2008 17:29:34 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3313?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12560007#action_12560007
] 

Kristian Waagan commented on DERBY-3313:
----------------------------------------

I created sub-tasks for what I believe will be the various parts of the statement pooling
feature implementation.
DERBY-3326 is expected to be the one requiring most work, and it is here the issues regarding
correctness, proper behavior and edge-cases will be handled.

Basic testing will be handled in each sub-task, and there might a separate patch in the end
with more complex tests.
I expect to provide patches for DERBY-3324 and DERBY-3325 first.

scenarios, for instance some multi-tier systems using connection pooling.
