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.

Updated SSO operator authentication handling after passivation
Resolved in Pega Version 8.1.9
With SSO enabled and the pyAccessGroupsAdditional value list populated with the Mapping tab, attempting to access an expired session with an old cookie resulted in a stale thread exception while mapping value list attributes. This was due to using an AuthServicePage which was created by another session thread that had become stale for current session, and has been resolved by updating the code to call the authenticateoperator method on the authservicepage copy.

Added handling for password containing a colon on Pega Client for Windows
Resolved in Pega Version 8.1.9
If a password included a colon (:), it was possible to log in on the desktop but not Pega Client for Windows. This was due to authentication files specific to the Windows mobility client, and handling has been added to resolve the issue.

New security role added to restrict access to development-specific classes
Resolved in Pega Version 8.1.9
A new security role and related RAROs have been implemented to allow better security for end users on non-BAC systems. This restricts access to Rules and execution of activities on classes that are development-specific.

CDK key loading modified for better database compatibility
Resolved in Pega Version 8.1.9
Users were unable to log on to the system and received the error "There has been an issue; please consult your system administrator." Investigation showed the log errors stating "(dataencryption.DataKeyProvider) ERROR localhost - Could not get CDK from systemKeyManagementCache - System CDK is null". This was an issue specific to the MS SQL Server database when there were 6 or more CDKs in the database: CDK keys are loaded from database into Cache using an SQL statement which had the ORDER clause. By default, the ORDER clause treats NULL values differently on different databases, and this caused MS SQL databases to not load a necessary CDK key. To resolve this, the SQL query has been modified so the result will be the same for all supported daatbases (Oracle, Postgres & MS SQL Server).
