Refinements made to MarkerNode memory use
Resolved in Pega Version 8.5
Significant memory usage can be observed when data join in strategies are missing the join conditions. E.g., when the primary source in the strategy can have up to 300 or even more propositions, the join without the join condition would perform a cartesian product with possibly up to 400 or even more records returned. This may cause performance degradation. To guard against this, an update has been made that seeks to prevent repetitive markers being accumulated under a MarkerNode while trying not to rely on any implementation of equality and hashCode for individual marker implementations.

Data Flow StartTime uses locale timezone
Resolved in Pega Version 8.5
The start time of the dataflow was displayed in GMT instead of the operator locale timezone. This has been corrected.

DataSet preview will use date instead of datetime
Resolved in Pega Version 8.5
While using a DataSet preview functionality, the date appeared as reduced by one day. This has been resolved by parsing date as 'date' instead of 'datetime' to avoid issues with timezone interactions.

pxIdentifier dynamically set for DecisionData while using GOS
Resolved in Pega Version 8.8
When using a Decision Data component in a strategy which was wrapped with Globally Optimized Strategy (GOS), no results were generated from the DataJoin shape under optimized execution. Investigation showed this was caused by a missing .pxIdentifier for the DecisionData shape during GOS execution. There was a workaround of unselecting the checkbox on the Advanced tab in the Decision Data component, but this has been resolved by updating the strategy kernel service so it will dynamically construct the pxIdentifier based on the skills assignment module (SSA).

Errors persisted for single case runs using a custom error handler
Resolved in Pega Version 8.8
Single case processing (SingleAccountData) had failed records when opening the SubscriptionData dataset, but it was not possible to see the failed record details for further investigation. Investigation showed that when running a single case run with a custom error handler, errors were persisted as part of the dataflow metrics, but not written to the database. To resolve this, an update has been made to ensure errors are persisted for single case runs configured using a custom error handler.

DelegatedRules refresh icon made accessible
Resolved in Pega Version 8.5
When using Accessibility, the refresh icon in pzDelegatedRules was being read as "Link". This has been corrected by adding text for the refresh icon.

Updated context handling for executing data transforms in dataflows
Resolved in Pega Version 8.8
When performing a sort operation in a data transform on a pagelist and invoking the Data transform through a Data flow, a java.lang.UnsupportedOperationException was generated on the sort step even though the data was correct. Investigation showed that the dataflows were using a different execution context than the context used for regular activity execution. An update has been made to ensure the correct context is being used while executing data transforms in dataflows.

DSS introduced to control DSM clipboard page serialization
Resolved in Pega Version 8.8
When using a Kafka dataset to consume a message from an external topic that had an attribute name with a special character contained in a page list structure, using a JSON data transform for the mapping in a realtime dataflow resulted in the error "Exception in stage: KafkaDS; LegacyModelAspectInvokableRuleContainer.invoke-Exception encountered a :java.lang.UnsupportedOperationException." To resolve this, a new DSS dataset/CLASS_NAME/DATASET_NAME/JSONDataTransform/deserialization/useDSMPage has been introduced. When the value is set to true, the process will follow the previous behavior of DSM clipboard pages being generated when Kafka records are deserialized using JSON data transform. When the value is set to false, the JSON data transform will generate regular clipboard pages and convert them later to DSM clipboard pages. This would avoid errors when a JSON data transform calls methods from the Clipboard API that are not implemented by DSM pages. This DSS is set per data set instance. CLASS_NAME and DATASET_NAME are placeholders which should be replaced by data set's pyClassName and pyPurpose property values. In addition, a similar DSS, dataset/CLASS_NAME/DATASET_NAME/JSONDataTransform/serialization/useDSMPage, has been introduced for serialization.

Timeout added for Cassandra writes
Resolved in Pega Version 8.8
When using Customer Decision Hub with external C* deployment, attempting to stop a data flow run which was reporting stale threads for some partitions resulted in some of the partitions continuing to run while threads were waiting on the Cassandra save operation. This has been resolved by adding configuration for a timeout when waiting for the results of the save operation, with a default of 300 seconds.
