Insert commands trigger parsing
--------------------------------
Key: HHH-5527
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-5527
Project: Hibernate Core
Issue Type: Improvement
Affects Versions: 3.2.6
Environment: Solaris 10 update 8, Oracle 11.0.2
Reporter: Mahendra M Gharpuray
Priority: Critical
While running several thousand concurrent inserts, we noticed a huge amount of parsing.
Upon detailed investigation, we found that the parsing was for select * queries tied to
the table into which inserts were happening. For each insert, there was a select * call
and that was parsed each time. This resulted in poor performance of the application.
Parsing was consuming 99% of database time leaving only 1% time for actual query
execution.
