DataSet-Execute updated to correct time-to-live error
Resolved in Pega Version 7.2.2
When using the time to live option of a Decision Data Store dataset, the java generation for the DataSet-Execute method was causing java compilation errors. This was due to an inconsistency between the code generation for DataSet-Execute method in an activity and the settings provided. To correct this, the algorithm used to generate the code for DataSet-Execute method has been updated to include the time to live setting and to generate correct and compilable code.

Enhancement for Facebook connector retrieval
Resolved in Pega Version 7.2.2
Whenever the Facebook connector was restarted, historical posts on the monitored page were being fetched and duplicate documents were getting harvested into the DB. To resolve this, a new search parameter has been added for the Facebook connector that will receive a date as parameter for how many period/days of historical data to fetch.

Improved cleanup for adm_response_meta_info
Resolved in Pega Version 8.6
The adm_commitlog.adm_response_meta_info column family was growing, leading to gradual increase in CPU utilization on the Adaptive Decision Management (ADM) nodes over time. Investigation showed that the compaction on the adm_response_meta_info table was not being triggered by the ADM service, and the compaction did not remove rows that belonged to models that had been deleted. To resolve this, compaction of the adm_response_meta_info table has been moved from the ADM client nodes to the ADM service nodes, which will correctly trigger the compaction on a predefined schedule. The compaction logic has also been refactored to remove rows that belong to models that have been deleted.

Thread contention resolved for InteractionHistoryQuery
Resolved in Pega Version 8.6
High thread contention was observed while running Inbound load tests. This was traced to pzLoadInteractionHistory invoking a generated strategy to retrieve ihFields from InteractionHistoryQuery using the getUsedInteractionHistoryFields() method: because this method is synchronized, it caused a bottleneck. To resolve this, the synchronized methods have been replaced with the appropriate data structures.

Strategy handling updated for very large systems using IH summary
Resolved in Pega Version 8.6
When a Strategy in a Real-time dataflow used IH Summary on a system with more than 5000 groups for one eventKey, the message "Error retrieving aggregates from Cassandra KVS" intermittently appeared. Investigation showed that if the number of result rows was greater than the FETCH_SIZE (set to 5000), it meant another read to Cassandra was required and an exception was generated. To resolve this, updates have been made so that instead of returning maps, the system will return iterators and change them to map on the calling thread.

Enhancement added for node heartbeat recovery process
Resolved in Pega Version 8.6
Nodes were not showing up in the admin portal even though they were up and running and could be seen in the pr_sys_statusnodes table. The exception "An exception was encountered while invoking the cluster membership listener callback" was seen. All nodes became visible again after multiple restarts. The root cause was traced back to a temporary database connectivity problem. The database itself was fine according to database monitoring reports, but a network problem, a slow database query, or another issue prevented Pega from establishing a connection for more than a minute. An enhancement has been made to resolve this: if a node becomes unhealthy due to the service registry missing due to a failed heartbeat, the heartbeat will try to recover after 60 seconds and keep trying every 30 seconds until it succeeds.
