Queens Series Release Notes¶
12.4.0-8¶
New Features¶
Add openstack-db tag to Exec that run db-sync.
Bug Fixes¶
Previously the number of heat engine workers was set to $::os_service_default which would use the default from python. Usually this means it will use the number of processors in the system. We have found that this is not an ideal default for large number of cpu systems. We have a provided fact specific to heat engine named $::os_workers_heat_engine. We have changed the default value for the heat engine works to use this fact. This fact will cap the value at 24 but usually is the larger of (number of procs / 2) or 4.
