Pega Catalog custom upload control modified
Resolved in Pega Version 8.5.3
Attempting to upload a catalog.zip file caused the system to hang and thread dumps were seen in the logs. Investigation traced the issue to the custom control used to upload the catalog, which was posting the entire content in form data rather than sending a multi-part request. The control contained both legacy code which used form.submit() and encoding along with new code that used SafeURL and sent an async request. With this, encoding could not be set to multi-part in case of an AJAX request. To resolve this, the catalog upload control has been modified to use the appropriate legacy code that performs form.submit() and sets the encoding properly.

Filter considers all instances pages during deployment
Resolved in Pega Version 8.5.3
During package deployment, attempting to use Filter to skip some of the instances only displayed the result of the current active page instead of all pages. This was an unintended consequence of previous work, and has been resolved by adding the logic to strip quotes in the value and adding the "Pagination activity manages filtering" checkbox by default.

Kerberos handling updated for database remap
Resolved in Pega Version 8.5.3
After upgrade from Pega v7.2 to Pega v8.4, using Kerberos authentication was failing during the remap task. Investigation showed that null username and password values were being passed to SchemaAssignmentUtility along with the flags as arguments, causing the utility to misinterpret the arguments. As arguments should be populated only when flags and values are available and not null, an update has been made which will set the username and password flags only if they are not null in the Remap database tables target.

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.
