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.

Upgraded Apache UIMA Ruta libraries to resolve memory leak
Resolved in Pega Version 8.6.2
A memory leak issue that resulted in a reboot being needed every few days was traced to the class org.apache.uima.ruta.rule.RuleMatch. This has been resolved by upgrading the Apache UIMA Ruta libraries to v2.8.1.

Removed redundant Microsoft Outlook email interaction chain
Resolved in Pega Version 8.6.2
When opening an email interaction case, the email editor user interface area showed the complete email chain of the email for every new message that came in related to the case. This was traced to the difference in the selectors that various email clients use to construct a response to an email with email history in it, and has been resolved by updating the selectors for Microsoft Outlook in pyRichTextEmailHistorySelector so no conversation is repeated when using that client.

Resource added to extract email threading code from message body
Resolved in Pega Version 8.6.2
In some scenarios the case ID was not being sent in the subject of email replies as expected, and the secure tracking code was part of the email body instead. That caused replies back to the email thread to create a new email interaction case instead of properly threading the new message into the conversation. Investigation traced this to some email clients removing space after the tracking code. To resolve this, an update has been made which will extract the tracking code from email-content html if it is found and otherwise fallback to the email body.

Added handling for reloading portal while ChatBot is active
Resolved in Pega Version 8.6.2
An issue was seen with UI rendering when a customer tried to reload the portal where the chatbot is deployed. Investigation showed that this was caused by the screen going to pyCreate harness instead of ChatPerform harness due tot he unexpected refresh, and has been resolved by updating the handling for the Chat Work page and the business case so that pyWorkPage is always Work-Channel-Chat.
