Steven Hawkins updated TEIID-2410:
----------------------------------
Summary: issues with output buffer blocking (was: add tuning for lots of
active plans)
Issue Type: Bug (was: Quality Risk)
Fix Version/s: 8.3
Affects Version/s: 7.7
Description:
when a local connection (regardless of using the calling thread) blocks on the output
buffer (which cannot happen with forward only and using the calling thread, but due to
another issue can occur with a scroll insensitive result) no corresponding process thread
is awakened to process pending work.
Output blocking should also be disabled for non-forward only results. This was disabled
at some point by a refactoring to reuse the output buffer from the plan.
was:When an active plan is not processing it will still be holding memory against the
buffer manager reserve count.
