Data Transform added to support Kafka custom serialization/deserialization
Resolved in Pega Version 8.5.1
Previously in a Kafka DataSet it was possible to either serialize or deserialize messages as mapped objects to JSON, or to implement some other mechanism to achieve the expected results. An enhancement has now been added to the Pega platform functionality: DataTransformSerde will be available to be used as custom serialization/deserialization mechanism in Kafka DataSet.

Improved cleanup for adm_response_meta_info
Resolved in Pega Version 8.5.1
The adm_commitlog.adm_response_meta_info column family was growing, leading to gradual increase in CPU utilization on the 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.

Performance improvements for very heavy use of strategy decision logic
Resolved in Pega Version 8.5.1
Updates have been made to improve memory performance for scenarios where a single request primary page had tens of thousands of pages under an embedded pagelist property and the decision logic involves a strategy running on all the pages in that page list. These include modifications to GetFramesSSA to create reusable frames under heavy load conditions that contain the information about all the primary pages that it has to iterate; if CallSsaProgram receives one of these special frames, it will use it invoke the program by repurposing it with a new primary page at each iteration.

Strategy handling updated for very large systems using IH summary
Resolved in Pega Version 8.5.1
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.

SaveAttachment Activity in Data-WorkAttach-URL updated
Resolved in Pega Version 8.5
A 'when' condition was not properly evaluated for Activity SaveAttachment (CL:Data-WorkAttach-URL ), causing the Next assignment screen to not be displayed. This has been resolved by modifying the handling of Page Names used as activity parameters to remove the use of the specific PageName "pyAttachmentPage" in the operation and make it generic to Primary in the SaveAttachment Activity of CL: Data-WorkAttach-URL.

Improved accessibility around page landmarks
Resolved in Pega Version 8.5
Accessibility testing revealed an issue with pages where the main landmark was contained in another landmark. This has been resolved by removing the main role in the FlowActionHTML rule.

FilterHistory decision tree used for audit log status
Resolved in Pega Version 8.5
Attempting to use the “FilterHistory” decision tree in the work class to return value “false” for “pyCloseOpenAssignmentsOnResolution” to hide the “pyCloseOpenAssignmentsOnResolution” field value (“Unfinished assignments were cleaned up by the system after the completion.. ”) from history was not working as expected, and still returned the audit message. This was due to the system setting this AuditNote parameter within the “pzProcessResolutionStage” activity, where Param.UpdateHistory was set to true always. In order to support more flexibility, the Param.updateHistory paramter in step3 of the pzProcessResolutionStage activity will be set based on the FilterHistory decision tree. When set to false in FilterHistory decision tree, pyCloseOpenAssignmentsOnResolution will be set as false and audit will not be logged.

Resolved erroneous problem assignment error
Resolved in Pega Version 8.5
If a user processed a work item while the SLA agent was also attempting to process it, it sometimes resulted in an assignment with the error: "Error: Flow Not At Task." In this scenario, an error message was displayed stating that "Assignment already completed" even though the assignment was not yet finished, causing confusion. Investigation showed that in cases where the success indicator was -28, the assignment was marked as problem assignment even though it was processed. To resolve this, the system has been updated to skip marking the assignment as a problem when the success indicator is -28.

Handling added for null requiredskillcount on assignment
Resolved in Pega Version 8.5
If the property pxRequiredSkillCount was blank on an assignment when moved to a workbasket, it was never presented for Get Next Work. To resolve this, handling has been added which will change the null to 0 so the assignment is properly queued.
