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.

Simulation can take Data flow type as destination

Resolved in Pega Version 8.1.9

Support has been added for Data flow functionality as simulation target and data transform in simulation input.

INC-120326 · Issue 564437

Landing page refresh modified to avoid frequent reloads

Resolved in Pega Version 8.1.9

Approximately every two weeks, clients were able to login but it was not possible to work as the landing page refreshed constantly until all of the nodes were rebooted and the issue was cleared. Investigation indicated the frequent reloads were related to the cacheing of the operator details, and this has been resolved by updating the datapage reload strategy based on 'when' so frequent reloads will be avoided.

INC-130158 · Issue 572051

iOS file attachment works in Safari

Resolved in Pega Version 8.1.9

Attaching PDF and images from iOS devices using Safari was not working. This was traced to iOS 13 launching the file browser by default if the file-input element had an accept=/ attribute value pair, and has been resolved.

INC-136752 · Issue 587728

Adding handling for custom image on S3 storage space

Resolved in Pega Version 8.1.9

When using an S3 repository for Content storage, trying to create a new space with a custom image did not upload the image. Investigation showed that when attachment storage is configured as an external repository, the pyAttachStream property which is used to create the the thumbnail was getting cleaned as part of the saving logic. This has been resolved by adding an update that will hold the attachStream value in a local property before calling attachment save.

INC-141920 · Issue 595139

Unable to delete the Spaces after loggin off

Resolved in Pega Version 8.1.9

If a Space was created and then deleted in the same login session, the delete worked as expected. If the Space was created and then actions were taken to delete it on a subsequent login, the Space was not actually deleted. Investigation showed this was due to v8.1 not having a stream/blob (PZPVSTREAM) in the pc_work_group table, and this behavior was the result of extra properties included on the page. To resolve this, the extra properties on the page will be removed before the obj-save/commit .
