Can one of the admins verify this patch? |
- Added READONLY support for PostgreSQL.
- Major rework for queries and statements used on monitoring tables:
+ Checks/Actions rewrote for single instance checks.
+ Reuse of prepared statements instance of re-preparation.
- Fixed missing error handling in connection creation state machine.
- Added support for configurable batching in scheduler thread, via
'*_interval_window' variables. These variables allows to define the
burstiness of the scheduling within the processing interval.
- Several fixes for 'poll' timeout computation for worker threads.
- Fixed edge cases for current interval detection.
- Reduced deviation in scheduling intervals computation.
- Refactored and simplified connection event handling.
- Honor '-M' argument for disabling monitoring support.
