Cassandra made more robust and dx logging enhanced
Resolved in Pega Version 7.2.2
The Dnode/adaptive logic worked as expected on an environment with a single node, but was working sporadically on a eight node setup and generated the "DNodeException: Cannot execute modification statement". After analysis it was determined that Cassandra was intermittently seeing the other nodes due to several issues: - Server is overloaded and cannot receive ping from other nodes - Network difficulties - Topology issues due to series of sporadic server restarts To resolve this, the system has been updated to retry Cassandra requests several times to account for temporary network issues and will provide more robust and detailed diagnostics information to help in problem solving.

DSM Operations Guide updated for Interaction History Database Tables setup
Resolved in Pega Version 7.2.2
The DSM Operations Guide has been updated to clarify that when setting up Interaction History Database Tables in a Dedicated SchemasetupDatabase.properties file, the argument should be dbDataSchema and not dbSchema as was given previously. Also, data.schema.name=PEGADATA entries will take precedence if already entered.

DSM service will not start in non-web environment
Resolved in Pega Version 7.2.2
The import of NBAA using prpcUtils did not terminate due to the DSM services threads not being properly shut down during program termination. As DSM service is not needed in this circumstance, DSM service has been fixed to not start in non-web environments such as prpcUtils or prgit.

Improved Extended Interaction History cache handling for column removal
Resolved in Pega Version 7.2.2
The Interaction History Component was generating an error when IH was extended with additional attributes in the transform rule:Data-Decision-IH-Configuration -pyInteractionHistoryConfiguration and then deleted at a later stage. Once the new property was mapped and the IHFact table was altered to add the new column, the Interaction History component in the strategy which retrieves the IH data was not able to handle the removal of that column from the IHFact table or from the data transform due to a static marker in the rule not being updated with the deletion. The cache function has been modified to correctly reflect the deletion of the column.

Proposition Filter performance improvement
Resolved in Pega Version 7.2.2
The logic for the Proposition Filter rule has been modified to not perform constant database lookups in order to get its requested information but rather to always pass the proposition data into strategy.

EventStore compiler save error fixed
Resolved in Pega Version 7.2.2
The Save Operation for pxEventStore in Activity was giving a compile error. This was due to an incorrect class/method being generated, and the event-store code which controls the custom Dataset-Execute params has been updated to resolve this.

ADM startup made more robust
Resolved in Pega Version 7.2.2
The Strategy execution was failing when the ADM server was unavailable. To support a more robust process, the server proxy will be wrapped with circuit breaker to prevent propagation of errors caused by ADM unavailability, and backup is no longer taken after reading event queue on ADM server startup (if failsafe on), but instead will just happen on next model update call (every 30 seconds). This is to reduce the window in which responses are lost when server is starting up.
