Performance improvements for stale thread warnings
Resolved in Pega Version 8.6.3
Stale thread warnings were causing performance issues during dataflow run execution. Stale thread/slow component warnings are added as part of the dataflow execution when a processing thread takes more than 5 minutes to process a single dataflow record. The stacktrace of the dataflow thread is added as part of the warning for debugging purposes, but in some scenarios the stacktrace can become very large. This has been resolved by removing the stacktraces from the warning, improving the query logic, and adding the run ID to the exception method to assist if there is an error.

File Dataset wildcards updated for ADM storage
Resolved in Pega Version 8.7
Attempting to access the filepath was failing and an error was seen indicating "Could not obtain lock 'Create repository file pegacloudfilestorage:ADM/Rule-Decision-AdaptiveModel/Data-Decision-Request-Customer". While creating a file name, a lock is generated while checking the file names of existing files. If the file data set has a large number of files, a condition may occur where some threads are unable to save data and an exception is thrown. To resolve this, the wildcard previously used in the file name has been replaced with the Pega node id + thread id + current timestamp. This will ensure all wildcards are unique and there is no need to lock and list existing files.

Case Archive updated to better prune email and attachment metadata
Resolved in Pega Version 8.7
After configuring pyPegaArchiver, pyPegaIndexer and pyPegaPurger to remove old cases, there were no records present in the pr_metadata table but the records related to Data-Corr-Email, Data-WorkAttach-File and Link-Attachment remained. As there is no harm in removing these entries because the system has already copied the reference to these attachments, the entry in pr_metadata can be removed without any issue. With this update, external and shared entries now get removed from pr_metadata table when a purge is performed, however they do not get removed from the target table.

Performance improvement for Application Save: Node Level Data Pages
Resolved in Pega Version 8.7
As part of new functionality introduced in 8.3, data types defined in the application record will be turned into data objects on Application save. As part of this process node level pages are invalidated and reloaded and there is an explicit commit that marks the Application record as dirty and sends any calls for the application record to the database for fresh records. In a multi-node environment, the number of queries to get the application record being saved became exponentially higher and performance impacts were seen. This has been resolved by updating the system to skip eager loading of the data page definition when an access rule or application definition is saved.

Save works on Ajax container without Dynamic container
Resolved in Pega Version 8.6.3
After opening a work object and making changes to a required field, pressing the save button did not give any visual indication that the save was performed. Hitting cancel generated a dirty pop up saying changes will be discarded, indicating no save was done. When an Ajax container is configured without a Dynamic Container, all the content is rendered inside a fieldset tag instead of a form tag. While performing the save, the API was looking for the form element in the document and could not find any, and the save failed. This has been resolved by updating the submitWhenFail() API to handle both fieldset and form elements in the dom.

Index table correctly populates after migration
Resolved in Pega Version 8.7
After creating a product file with work instances, only some records were populating in the index-workpartyuri class through index rule. Investigation showed that if the IDs specified for the Work Range started with the same digits as were seen after the case prefix (e.g. W-1, W-1000, or W-22, W-2201) then only the indexes for cases that start with W-1 or W-22 were included in the export. This was traced to a step in AddPartyIndexWhenCondition where the EstimatedWorkPrefix local variable was calculated: the java step extracted anything that was the same from the start of the To and From range without taking into account the possibility that some digit characters after the "-" could be the same. To improve the accuracy of the prefix estimation, "-\d" will be used to make an educated guess.
