PropertyToColumnMap made more robust
Resolved in Pega Version 8.1.9
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.

Behavior made consistent between SSA and legacy engines
Resolved in Pega Version 8.1.9
There was a behavioral disparity between the legacy execution engine and the SSA engine where the latter was not creating a new page when the index was one above the size of the page list. This has now been corrected in order to make the SSA behavior fully backward compatible with the legacy engine, i.e. a new blank page will be added to the list if the index is one above the size of the list.

Handling improvements for commit logs
Resolved in Pega Version 8.1.9
The ADM commit log logs the number of unconsumed messages that are going to expire. In certain circumstances, it can include unconsumed messages that are not going to expire in the count. Because they are not expired and removed, the environment was running out of disk space due to the ADM commitlogs table growing larger than expected and performance issues were seen. To resolve this, a new adm_commitlog.adm_responses_commit_log_date_tiered table has been created, with a default_time_to_live of 24 hours. DateTieredCompactionStrategy has been set with max_window_size_seconds as 24hrs and tombstone_compaction_interval as 24hrs.

Performance improvements for Test Strategy data flow
Resolved in Pega Version 8.1.9
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.

Strategy handling updated for very large systems using IH summary
Resolved in Pega Version 8.1.9
When a Strategy in a Real-time dataflow used IH Summary on a system with more than 5000 groups for one eventKey, the message "Error retrieving aggregates from Cassandra KVS" intermittently appeared. Investigation showed that if the number of result rows was greater than the FETCH_SIZE (set to 5000), it meant another read to Cassandra was required and an exception was generated. To resolve this, updates have been made so that instead of returning maps, the system will return iterators and change them to map on the calling thread.

Added deferred loading for email cases
Resolved in Pega Version 8.8
When there were a significant number of email interactions on an email case, delays were seen when loading the case in the UI. Investigation traced this to a high number of database calls along with the BLOBs also being open. To improve performance, the new rule pyDeferLoadEmails has been added which toggles the UI and loads emails faster. In addition, the button label has been modified to read "View all emails" in place of "Show all" while defer load is enabled.

GetAllEmailWork temp page renamed to avoid conflict
Resolved in Pega Version 8.8
The default Email manager portal was not displaying new email triage cases. Investigation showed that because the GetAllEmailWork and CaseBreadCrumbPopulate activities were using a common name for the clipboard page "TempPage", when CaseBreadCrumbPopulate removed the TempPage clipboard page as one of its steps a null pointer exception occurred for GetAllEmailWork. To resolve this, an update has been made to rename "TempPage" to "TempPageET" for GetAllEmailWork so the names will not conflict.

Handling updated for social messaging items with very large embedded images
Resolved in Pega Version 8.8
Job scheduler was running out of memory while handling large/multiple files, causing nodes to crash while handling Social Messaging items. Inline images were also not being sent in the ACK email. Investigation traced this to a custom job scheduler and activity used to create PDFs from email communication and send the PDFs to a third-party system. This used the standard Email Triage/PegaSocial functionality for the emails, which were stored as instances of PegaSocial-Message. The custom Job scheduler and activity then leveraged the Data Page D_pxEmailPosts to retrieve the emails in order to harvest the text from the emails. The issue occurred when a number of the emails had multiple or large embedded images in them, meaning the PegaSocial-Message instances are very large. This resulted in the node running out of memory and crashing. To resolve this, code has been added to support inline images in ACK email and the complete message from Pulse will be used instead of the original message as the email body for the ACK email.

Corrected intelligent routing in email channel
Resolved in Pega Version 8.8
Intelligent language-based routing in the email bot channel was not working as expected when given a condition to direct messages to a different operator based on language. Messages were placed in the Inbound Correspondence work basket instead. This was traced to the getRoutingActions API using the incorrect property from .pxAnalysis, and has been resolved.
