Logging simplified to improve performance issues related to PEGA0069 alerts
Resolved in Pega Version 7.3.1
In order to improve system performance in installations where many PEGA0069 alerts are logged, no data will be output for the "lastInput" field of the alerts. "Last input" field is typically populated with useful information that helps end user to analyze where the issues lie, but the field does not hold value in the context of PEGA0069 alerts.

Performance improvements for metadata queries with Oracle12c
Resolved in Pega Version 7.3.1
Performance issues with metadata queries were traced to a bug in Oracle 12c which caused the query to be executed multiple times instead of checking for the presence of table from tableInfo map. To improve performance, the logic in DatabaseImpl.getColumnsForUndefinedTable() has been modified to ensure the query executions will not happen with out looking at the tableInfo from map.

Improved MinConnections handling and performance
Resolved in Pega Version 7.3.1
The MinConnections setting in prconfig was not being considered by the connection manager, and some performance issues were seen due to the system closing and reopening a connection when a duplicate key exception was encountered. This has been corrected by modifying the connection manager to correctly consider the MinConnection value provided, and by improving error handling so that time is not spent making a new connection after an exception is encountered. In addition, DB trace events will be generated for closeConnection events.

Marketing data flow run made more robust
Resolved in Pega Version 7.3.1
After upgrade, it was observed that Pega Marketing Campaigns were failing if there were no customers in the Audience configured on the Campaign, generating the error message "The run failed, because it exceeds the maximum number of failed records, which is currently set to 0". The cause of this was executing a distributed data flow with a database as primary source on an empty table, leading the run to fail as a table without any partition was considered in the handling. The database dataset has now been updated to differentiate the case when there's no partition available from the case when there's a single partition for every record, ensuring the DB data set now returns 'all' records when there is no partition key defined, and the data flow handles the no values for partitions in a more robust way.

Serialization fixed for multi-node pre-activity dataflow
Resolved in Pega Version 7.3.1
Attempting to trigger a dataflow run with pre-activity configured to run on every node was failing with a serialization exception. This was caused by the task being distributed across the cluster having a member variable that was not serializable; this has been fixed.

Reworked destination assumptions for child dataflows
Resolved in Pega Version 7.3.1
When activating a Real time data flow run containing a Stream dataset as input which was then output to two child dataflows containing different event strategies, an IllegalArgumentException error appeared. This was traced to the pzDataFlowContainsEventStrategy activity assuming that the last shape had "Destination" in the ID. This has been fixed by properly setting the KVS type: the DataFlowRunConfig.getKeyValueStoreType() will not return NONE but will default instead, and the pzDataFlowContainsEventStrategy now Iterates through all subflows and fixed secondary destination name.
