Enhancement added for node heartbeat recovery process
Resolved in Pega Version 8.5.1
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.

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.

Encrypted SOAP response token generation updated
Resolved in Pega Version 8.5.1
After configuring a SOAP service that used signature and encryption on the response, the response being created was incorrect and could not be decrypted by the receiver. Investigation showed that the API used to generate the SOAP headers was not setting the wsse11:TokenType element, causing receivers which enforce BSP compliance to fail. This has been resolved by modifying the custom webservices-rt-pega2 jar to set the token type in the case of a response encryption policy.

Handling added for samesite cookies with httpOnly
Resolved in Pega Version 8.5.1
After enabling samesite cookies on Google Chrome to support Mashup login, intermittent issues were seen with a non-mashup login where entering the OperatorID and password only resulted in a refresh of the login screen. This was traced to a scenario where an httponly cookie attribute was present along with samesite cookie attributes, and has been resolved by adding handling for a condition where samesite is set and httpOnly is enabled.

Null checks added for the presence of roles and dependent roles
Resolved in Pega Version 8.5.1
Frequent Null Pointer errors were being generated relating to SecurityAnalysisForSecurityAdministratorsTask.getCurrentSecurityTaskDetails(). Investigation showed that the Origin and Stack trace tabs were empty, leading to the obj-open of the role failing when the role was not available in the system being utilized. This has been resolved by adding a series of null checks for role existence and dependent roles existence.
