[JBoss JIRA] (TEIID-3110) name in source should not be omitted in ddl
by Steven Hawkins (JIRA)
[ https://issues.jboss.org/browse/TEIID-3110?page=com.atlassian.jira.plugin... ]
Steven Hawkins resolved TEIID-3110.
-----------------------------------
Resolution: Done
To prevent this from being a breaking change, stopped omitting the name in source and updated the rest of the translator logic to be more consistent.

--------------------------------------
The entries (or entry) are not removed when queue.remove() is called. I will log the size of the queue in doEvictions(), I am using queue.getSize() method to get the size.

Steven Hawkins commented on TEIID-3106:
---------------------------------------
> This strikes me as odd but there could be good reason for it.
I think the intention was to allow the gets from the lower level cache to be purged after completely new entries, but a later change split the eviction queues into a two queue system so it's not really necessary.
> Do you think any specific info would be helpful ?
Perhaps some metrics on the eviction queues, such as the size. Are you still seeing that removal and/or eviction not working for the entries or is it just that a lot of time is being spent in removal? What jvm are you on? Older JREs have an issue with ConcurrentSkipListMap scaling.
