Data Flow correctly handles table encountering null numeric columns
Resolved in Pega Version 7.2
When a data set was created on top of a exposed table which contains some null value in numeric columns, a Data flow executed using that data set used the value '0' instead of the expected null property. This was traced to the Data Flow batch run execution using the DSMClipboardPages, which weren't able to differentiate if a property was present or not and led to null being mapped to 0 in a numeric property. To correct this, the NativeSQLAPI will return null values as empty values when querying a DB and will not use them populate a DSM page or propagate them in the data flow.

Performance tune-ups in DSM
Resolved in Pega Version 7.2
Strategy Profiler was showing misleading timing information for Switch, Champion Challenger, Exclusion, and Data Join. This has been fixed. In addition, Strategy Set has been optimized to let it evaluate the customer-specific expressions once per component execution (instead of per SR page) , and it will not clone SR pages if it's unnecessary. The Prioritization shape has also been improved to only prioritize the Top N if that?s configured.

Fixed NPE for Tracer
Resolved in Pega Version 7.2
It was not possible to execute strategies if the tracer was turned on. This was failing because the tracer was trying to collect the primary page in XML format from a clipboard page that was missing the implementation to generate the XML. This has been corrected.

Corrected implementation for DataFlow key non-match
Resolved in Pega Version 7.2
If a DataFlow Dataset configured against a Report Definition had a property key name that was not identical to the column name in the database table, the Dataflow failed to execute with error " Incorrect implementation for Report Definition as a data flow source. Property-to-database table column mapping was not applied correctly". The implementation has been fixed to resolve this issue.

External Cassandra nodes listed in DDS cluster
Resolved in Pega Version 8.3.1
Nodes of an external Cassandra cluster were not listed in the DDS cluster except for the first one in the host list, and when the “only” listed Cassandra node was restarted, the status on the DDS cluster LP did not become “NORMAL” afterwards. In addition, even though other C* nodes were up and running, the external Cassandra cluster was reported as unreachable. This was an unintended side effect of work done on the landing page to reflect the real state of the nodes after some were killed and restarted, and has been corrected by refining the equals() and hashCode() methods for DDS member info in order to better differentiate the external Cassandra nodes.

IH summaries working with external Cassandra
Resolved in Pega Version 8.3.1
Summaries were not working for external Cassandra. This was an issue with the IH summary component using the aggregated dataset as a reference, and this fix contains several components to improve this function. An issue where the IH aggregates dataset does not materialize when DDS is external Cassandra has been resolved by modifying the code that checks the DDS availability. A filter that was used to match “” did not work when pre-aggregation is off : this was due to the IH Browse operation being done outside of a DF context, and has been fixed. The IH Summary shape not working properly in a strategy if it referenced an aggregate dataset with pxInteractionID as part of the group-by properties was traced to an issue with it generating a pxInteractionID value when executing the strategy, and has been resolved by excluding pxInteractionID from the group keys in the IH Summary shape.

CEP bucket size increased to 1 minute
Resolved in Pega Version 8.3.1
Frequent DSM Data Flow Errors were observed in production nodes with very high event rates. This was traced to the default bucket size for CEP being 1 second for a 31 day window, which was not sufficient to handle high volume use which may create an event strategy window large enough to hit the Cassandra column size limit. In order to resolve this, the default bucket size has been increased from 1 second to 1 minute.
