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.

Email history will be stripped from case replies
Resolved in Pega Version 8.4.4
When sending an email reply to a case, the entire email history (all previous emails in the email chain) was attached to the case as part of the reply.To resolve this, updates have been made so the system will strip history only when it's a follow-up mail. In addition, an issue with duplicate attachments has been corrected, and attachments from trailing mail will not be copied to a new post.

Support added for email addresses with hyphen in domain name
Resolved in Pega Version 8.4.4
When attempting to enter a email with a hyphen '-' in the domain part of an email ID ([email protected]), the reply button was getting disabled. This was caused by the regex validation implemented in the "pzValidateEmailAddress" (Work-Channel-Triage-Email) standard activity not covering all the possible cases. To resolve this, regex has been changed to instead use a platform-provided rule to ValidateEmailAddress.

New email template added to include full message history
Resolved in Pega Version 8.4.4
Whenever a reply was sent from the email triage case, the outbound email sent only the actual reply along with the original email and latest reply only, skipping all remaining replies from email. For example, if there were 5 replies from case, replying 5th time generated an outbound email that contained only 5th reply (actual / current), original reply (which created the service case) and the latest reply (reply 4 in this case) and skipped reply 1 and reply 2. To resolve this, a new Outlook-style template has been added for use in replies that will include all of the previous exchanges.

Updated handling for unexpected character set in non-UTF-8 email
Resolved in Pega Version 8.4.4
After upgrade, the listener properly created a case from an email, but the space character was being replaced by ? in the inbound emails. Investigation showed the messages did not appear properly in the UI if the email was sent using any encoding other than Unicode (UTF-8) and it had a special character set. To resolve this, the system will remove the attachment type which includes the charset.
