Re-save case type completes successfully
Resolved in Pega Version 8.7
Checking in a case type rule with Stage Rule reference was failing. This was traced to the RuleCheckin activity being called in a nested fashion that caused an inner run to remove the "pyOriginalRecord" page which was needed in the outer run to set the .pyRuleset property (at Step 34), and has been resolved.

Handling added for special characters in dataflow and mbean name
Resolved in Pega Version 8.7
Exception errors from deleted email listeners were seen after server start-up. Investigation showed that when a dataflow stage name had a special character and that name was then used in the mbean name, it was failing to register. This has been resolved by escaping JMX key values if they contain special characters.

Value Finder updated for use with external Cassandra nodes
Resolved in Pega Version 8.7
Attempting to use the Value Finder feature resulted in the error "Running Simulation is not possible because the required services are not available. Contact your System Administrator to enable the data flow and decisioning data store services." Analysis traced this to a check which identifies whether there is more than one internal node available for CDH/ DSS node. Since there were only external nodes available in this scenario and no internal nodes, the method returned false and returned the error when the CDH / VF page was launched. To resolve this, the check has been modified to allow for external Cassandra.

Prediction outcome response timing updated
Resolved in Pega Version 8.7
Predictions using a response timeout were not emitting a negative response ('NoResponse') when the specified waiting time expired. This was traced to the the outcome and response timeout values being overridden while triggering responses for multi stage predictions along with chained predictions. This has been resolved by modifying the flow to emit each outcome as it is received and by adding the dataflow trigger in the function so that it does not override the values in case of chained predictions.

Tombstone cleanup modified to handle very large volume environments
Resolved in Pega Version 8.7
Cassandra nodes were periodically suffering from an out of memory condition. This was traced to tumbling windows creating too many tombstones for Cassandra to clean up effectively when running in a very high volume environment with a short tumbling time. This has been resolved by modifying the procedure away from using individual tombstones to instead use range tombstones which will continuously supersede the previous tombstone so there is never an opportunity for them to build up.

Performance improvements for action check-in
Resolved in Pega Version 8.7
The process of 'Saving As' an action to a higher ruleset, Saving, and then running Check-in was taking an excessive amount of time. This was traced to redundant page copy activities and performance has been improved by updating the implementation.

Performance improvements for stale thread warnings
Resolved in Pega Version 8.7
Stale thread warnings were causing performance issues during dataflow run execution. Stale thread/slow component warnings are added as part of the dataflow execution when a processing thread takes more than 5 minutes to process a single dataflow record. The stacktrace of the dataflow thread is added as part of the warning for debugging purposes, but in some scenarios the stacktrace can become very large. This has been resolved by removing the stacktraces from the warning, improving the query logic, and adding the run ID to the exception method to assist if there is an error.

Decision table null input handling updated for backward compatibility
Resolved in Pega Version 8.7
After upgrade, any null values as inputs in the decision tables were skipped if "Allow Missing properties" was not checked. This behavior was different from previous versions. In order to improve backward compatibility, the new function pxEvaluateDecisionTable has been added which has an additional parameter to set AllowMissingProperties, and the older function logic has been modified to take the parameter value from the parameter page.

Support added for connect-SOAP run in parallel mode
Resolved in Pega Version 8.7
When connect-SOAP was configured to use the “run in parallel” mode, application settings derived through a datapage had incorrect values. While running the connect-SOAP through an activity, all the values were derived incorrectly. This has been resolved by adding a synchronization enhancement to support parallel run connect.SOAP.
