Improved management for table pr_log_dataflow_events
Resolved in Pega Version 8.5
The Lifecycle event table was sometimes growing too large. This additional strain of database transaction volume caused poor performance on the Dataflow tier and lead to cluster instability and time-consuming cluster restarts. Due to problems in one of the Pulse tasks, the Pulse thread was not processing single case metrics properly and causing the unbounded queue for single case to grow. This has been addressed by switching to a fixed queue size, which is configurable with the DSS: dnode/single_case_queue_size. The default value of the DSS is 4000, and if changed a system restart is required. An error will be logged each 1000 queue misses, and metrics will be dropped if the queue is full. In addition, the Pulse task frequency has been improved and managed to prevent interference with other Pulse tasks and will be triggered only if a run is system-paused for a long interval. Rebalances now have a failsafe if something unexpected happens during the Pausing of the run, and If the cluster becomes unstable, the life cycle events logs may be disabled with dataflow/run/events/persist .

Properties persist after revision import
Resolved in Pega Version 8.5
When properties were added to a form, they sometimes disappeared after revision import even though the properties always remained visible in a strategy. Investigation showed that the Form changes made in a DD rule were not properly updated in the pyEditElement section. To correct this, logic has been added to handle the form changes in the DD in the following activities: Data-Rule-Summary.pyMergePropositions Data-Rule-Summary.pyRemoveDDRules Data-Rule-Summary.pyWithdrawDDChanges Data-Rule-Summary.pyRemoveRestoreDDRule

DataSet preview will use date instead of datetime
Resolved in Pega Version 8.5
While using a DataSet preview functionality, the date appeared as reduced by one day. This has been resolved by parsing date as 'date' instead of 'datetime' to avoid issues with timezone interactions.
