Updated dataflow used after pause/continue
Resolved in Pega Version 7.4
When using an event dataflow that has a Kafka dataset as the source, running the flow, pausing it, and importing updated rules was resulting in the resumed flow still using the old rules. This was a known limitation in the data flow metrics management where when a run was resumed, the previous metrics were "merged" with new metrics. In cases where the structure of a data flow changed between pause/resume, merge failed silently and new metrics were not saved to the database. The metric management has now been updated to merge metrics correctly: in case of a data flow structure update (e.g. shapes added/removed), after the data flow is run, stage metrics will be cleared up as it is not possible to match them with the new structure, and all other metrics will be properly resumed from the "paused" position (e.g. number of processed records, throughput etc.).

PropertyToColumnMap made more robust
Resolved in Pega Version 8.2.8
The DF_ProcessEmails dataflow was intermittently failing with a StageException error. This was traced to schema changes being propagated asynchronously by system pulse, which seem to have caused PropertyToColumnMap to cache stale schema. To resolve this, if the property mapping is not found the first time, the system will make a second attempt to get the mapping. Additional logging has also been added for better diagnostics.

Able to add offer to Change Request after deleting other offer from the landing page
Resolved in Pega Version 8.2.8
A Change Request creation was failing after deleting an offer rule from the revision management landing page. While deleting the offer rule, the activity pyDeleteRuleFromLP is called and pxDeleteRecord API is used to delete the rule. The pyWorkPage is being modified with class Work-ProjectManagement-CheckIn when the pxDeleteRecord activity is executed, but after this, the Change Request creation failed due to the wrong context of the pyWorkPage. This has been resolved by adding Page-New of pyWorkPage conditionally.

Improved cleanup for adm_response_meta_info
Resolved in Pega Version 8.2.8
The adm_commitlog.adm_response_meta_info column family was growing, leading to gradual increase in CPU utilization on the ADM nodes over time. Investigation showed that the compaction on the adm_response_meta_info table was not being triggered by the ADM service, and the compaction did not remove rows that belonged to models that had been deleted. To resolve this, compaction of the adm_response_meta_info table has been moved from the ADM client nodes to the ADM service nodes, which will correctly trigger the compaction on a predefined schedule. The compaction logic has also been refactored to remove rows that belong to models that have been deleted.

Strategy restoration repaired
Resolved in Pega Version 8.2.8
Once a strategy was deleted, it could not be restored afterward and a validation error appeared. This was an issue with some rule components being erroneously marked as required, and has been corrected.

ADMSnapshot agent defaults to running on a single node
Resolved in Pega Version 8.2.8
The ADMSnapshot agent runs when ADM is used, and should be run on only one node to prevent duplicate snapshots being created. To ensure preferred behavior, the "Run this agent on only one node at a time" option has been selected by default for ADMSnapshot agent.

DSS added to control monitoring data mart purge
Resolved in Pega Version 8.2.8
An enhancement has been added to automatically purge older data in the monitoring data mart at regular intervals so that it doesn't grow large enough to cause a lack of space or cause stress on the database resources. This is handled through the DSS decision/monitoring/daysToKeepData; the default is six months.

Performance improvements for Test Strategy data flow
Resolved in Pega Version 8.2.8
In the Test Strategy panel under Single case -> "Settings", selecting the "Data flow" option and choosing CustomerData dataflow was taking an excessive amount of time to run on a system with an extremely large database. To improve performance, two areas have been addressed: 1) the default behavior for record key suggestions in the test panel has been modified to collect only the ID as the additional data is not necessary at that time; 2) a DSS has been added that will opt out of reading and collecting the customer IDs in order to minimize data stored on the clipboard.

Improved performance for WebTreatments
Resolved in Pega Version 8.2.8
When there were a very large number of treatments propositions in WebTreatments DDR, one analyst trying to save a Treatment caused another analyst to get a DDR locked error. This was traced to the save process for a Proposition taking an excessive amount of time, and has been resolved by modifying the pzModifyDDRule activity to handle cleanup of the pxResults page on edit/update of a decision data rule.
