Description Joseph Marques 2009-08-11 20:00:00 UTC
this will be put in the 1_2_0 perf branch, and if results are positive will be forward-ported into trunk.

Comment 1 Joseph Marques 2009-08-11 20:03:08 UTC
branch RHQ_1_2_0_GA_PERF: rev4859 - use cached value for agent-is-backfilled; 

Comment 2 Joseph Marques 2009-09-03 06:48:53 UTC
rev5077 -  use cached value for agent-is-backfilled logic; 

during dbupgrade, make sure all rhq_agent.backfilled columns have values before setting the column to non-null; 
only set agent backfilled if the bit is actually flipping to reduce number of writes in steady state; 
move the setting of agent backfilled to false into availabilityManager.updateLastAvailabilityReport, which executes in its own xaction; 

Comment 3 Joseph Marques 2009-09-03 06:52:15 UTC
rev5078 - always make sure that setting of the agent backfilled bit occurs in a new transaction;
