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.

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.

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.

Setting added to customize using blank Map values
Resolved in Pega Version 8.7
After upgrade to from Pega 6 to Pega 8 some of the Map Value rules were not working. This was due to the handling for blank default values which was changed in Pega 7. In order to support backwards compatibility, a new 'when' rule has been added which allows customizing whether or not blank values are allowed for the Map value default columns. pyAllowBlankValues will default to "false".

Improvements for Offer Eligibility rules loading time
Resolved in Pega Version 8.7
After opening the Proposition filter/Action rule and clicking on Add Criteria, the pxAnyPicker drop down load was taking an excessive amount of time. Performance improvements have been made by adding a precondition at step 2 to avoid data page refresh for specific scenarios when it is not required.

SmartpromptType classes shown in Rule-Admin-Skill
Resolved in Pega Version 8.7
Some class instances were not showing in SmartpromptType list. This was traced to the activity LookUpList, which is called from Rule- class in Rule-Admin-Skill, using pyClassName as one of the filter criteria in Java Step1. Therefore Rule-Admin-Skills did not show in SmartpromptType list. This has been resolved by overriding LookUpList for Rule-Admin-Skill class so it will not consider pyClassName as a filter criteria.

Regex corrected for USZipCodeExtended validation
Resolved in Pega Version 8.7
Edit Validate - USZipCodeExtended was not working as expected. Instead of validating 5 numbers followed by 4 numbers, it was validating for 5 numbers followed by 5 numbers. This has been corrected.
