Repository APIs optimized to process large number of files
Resolved in Pega Version 8.5.1
When trying to delete 400K+ files in the attachments folder in a Pega Cloud Storage repository, the D_pxDelete API appeared to hang, though files were eventually deleted after an extended amount of time. The same API worked well when the folder had around 200 files in it. Previously, the D_pxDelete and D_pxListFiles APIs implementation did not consider the large scale inputs or outputs. This has been resolved by optimizing the performance of the recursiveDelete operation for S3 repositories.

Added handling for accessibility in SocialFilePath
Resolved in Pega Version 8.5.1
After configuring pxFileUploadGadget with the controls 'pzFileNameText' and 'pzSocialFilePath', moving the focus from the first control to the second required two presses of the tab key. This was traced to pzSocialFilePath having an input with type file, which is used in the background but not shown in the UI. To resolve this, tabindex = -1 has been added for the input to facilitate the accessibility.

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.

New security role added to restrict access to development-specific classes
Resolved in Pega Version 8.5.1
A new security role and related RAROs have been implemented to allow better security for end users on non-BAC systems. This restricts access to Rules and execution of activities on classes that are development-specific.

Operator created with save-as has correct application access
Resolved in Pega Version 8.5.1
Creating an operator using Save As retained access to the applications of the original operator even if they were removed in the creation process. This was due to the saveAs operation of the Operator not retaining consistency between the records in the ValueList pyAccessGroupsAdditional and the page list pyaccessgroups_opid. To resolve this, the PreSaveAs of the Operator ID has been updated to maintain consistency in the records.
