Resolved thread deadlock for rules upgrade process
Resolved in Pega Version 8.2.6
Platform upgrade was getting hung during the rules upgrade process. This was traced to a deadlock related to the conclusion cache entry for a property needing to make a call to declarative cache, where it tried to hold a read-write lock on a resource that was already locked by another thread. This has been resolved by replacing lock with tryLock to avoid deadlock.

Performance improvement for queries on Kafka partitions
Resolved in Pega Version 8.2.6
Even though there were multiple dataflow nodes available in the cluster, all requests were going to single node and causing system slowness. Investigation showed there was a queue processor rule that included the pxPartitionKey attribute which forced all records to be sent to a single partition by Kafka producers. This attribute has been removed.

ClusterAndDBCleaner repaired
Resolved in Pega Version 8.2.6
An error in the logic order of events caused a compilation error for pyClusterAndDBCleaner, leading to old records created by the system/node utilities to not be automatically removed as expected. This has been corrected.

Added support for JSON mapping of deep nested pagelist objects
Resolved in Pega Version 8.3.2
An exception occurred when using a JSON data transform in the service activity to map the clipboard data to JSON on the third level of a structure formed as Pagelist-->page-->pagelist. To resolve this, support has been added for nested pagelist mapping with deep nesting of objects (configured for one sided actions) and arrays.

Transient property passivation handling improved
Resolved in Pega Version 8.3.2
Frequent "com.pega.pegarules.pub.PRRuntimeException" errors were seen in the production log file while working on the WO. This was traced to corruption in the blob caused by transient properties during passivation. To resolve this, corrections have been made to the handling for the transient property entries in the blob.

Queue Batch activity correctly passes chlld process access group
Resolved in Pega Version 8.3.2
Attempting to create an index using the schema tools landing page was throwing an error in the table history stating "Create index failed". Investigation showed that this happened when a user was authenticated without the PegeRULES:DatabaseAdministrator role and then switched to an Access Group with the PegeRULES:DatabaseAdministrator role. The issue was traced to the activity that launched the batch requestor missing the parameter pzUseCurrentAccessGroupForChild due to the Queue Batch activity only passing the default access group authorization. This has been resolved by adding code to pass the additional authorization which will allow users to create an index in this scenario.

DSS setting added to Invalidation query to tune performance
Resolved in Pega Version 8.3.2
Running a RuleInvalidation query on an SQLServer database with a large amount of data was causing performance issues. To improve performance, a force order hint has been added which can be enabled with the DSS setting racache/useForceOrderHintForInvalidationQuery.

DSS added to Request Only Connect SOAP for Robust
Resolved in Pega Version 8.3.2
After upgrade, creating a new SOAP integration set to "Request only" in the Service tab and then running the activity showed requests coming with no response, then failure after three tries. This was traced to previous changes made to support Robust behavior and log failed asynchronous calls, and has been resolved by modifying the Robust support and moving it to a DSS. If “EnableRequestOnlyFaultMapping” is set to “true”, then the ANON_ROBUST_OUT_ONLY_OP option will be used; otherwise, the default behavior will be ANON_OUT_ONLY_OP.

Enhancements added for using AWS file repositories
Resolved in Pega Version 8.3.2
Enhancements have been added to improve the use of AWS file storage: Logging for AWS SDK connection metrics can be activated on a per-repository basis, either through the ruleform or through the DSS storage/class/:/enableMetrics. INFO logging can be enabled on PegaAWSSDKMetricReporter to periodically output averages of recorded metrics for all registered S3 repositories with metric collection enabled, or INFO logging can be enabled on PegaAWSRequestMetricCollector to output recorded metrics on every client call for all registered S3 repositories with metric collection enabled. The interval at which PegaAWSSDKMetricReporter logs metrics at can be configured with the DASS storage/AWSSDK/metricReportingInterval. This DASS is a system-wide setting, and not a per-repository setting. The default reporting interval is 90 seconds, and metric collection is disabled on all repositories by default.
