Resolved Cassandra query read/write latency
Resolved in Pega Version 8.2.8
Read/write latency was seen when certain Cassandra queries were triggered by the system. This was traced to an unusual case where a flush was not done for an exceptionally long time period, and has been resolved.

Support added for expression in strategy scorecards
Resolved in Pega Version 8.2.8
When invoking REST against a dataflow that had a strategy containing a scorecard that used an expression and the "Include model explanations option" was enabled in the Strategy configuration, the system failed with the error "PropertyValueInvalid .pxMaxScore Cannot cast the value (unknown) to double". This was traced to the Scorecard explanations failing during serialization when an expression was used, and has been corrected.

Oracle database performance improvements
Resolved in Pega Version 8.2.8
When the IH Summary was enabled and materialized on an ADM model, updating the ADM model was very slow on large sites. This has been resolved by adding several performance improvements for working with Oracle databases, including Oracle pre/post processing steps.

Handling added for Oracle Aggregate IH Summaries
Resolved in Pega Version 8.2.8
When using using (Non Materialized) IH Summaries to aggregate IH data, the data returned by the IH summary did not include all the expected records. If the same criteria was executed on the database via SQL or by using a strategy to process raw IH data then the results were as expected. This was due to a difference in handling of Oracle vs postgres which causes an order by clause not to be generated in the query: the postgres column name is lower case, while in Oracle it is upper case. This has been resolved by updating the system to get the column name correctly from the propertytocolumn map so IH records are returned in correct order by Browse By Keys operation.

Data Flow correctly saved to Database table Dataset
Resolved in Pega Version 8.2.8
After setting up a dataflow with Report definition as a source and Database table dataset as destination with the option "Insert new records and override existing", a data transform was used to modify a few of the values and write to the same database table. This table was mapped to pegadata schema and didn't have a pzpvstream column. Running the data transform generated an exception stating "DataStoreSaveStatementWithoutStream(PageDatabaseMapperImpl). The error was not seen when the pzpvstream column was added or if pzInskey was also removed along with pzpvstream, or if "only insert new records" was selected. This was traced to pzInsKey and pxInsName being null in the query formed while writing. There are two execution paths for the database dataset save operation, one for internal tables and another one for external tables. For a table with pzInskey but no blob, the system was incorrectly using the external table logic. This has been corrected.

Orphaned CSS reference removed from DisplayReport harness
Resolved in Pega Version 8.2.8
An intermittent invalid CSS error was appearing in the DisplayReport harness when an operation resulted in the regeneration of the harness content. This was traced to a reference to the workform_pyReportingSkin CSS, which was used in old reporting features and is not in use anymore. The reference has been removed to resolve this issue.

Corrected reference exception for filter on a grid sourced from a parameterized report definition
Resolved in Pega Version 8.2.8
An Invalid Reference Exception was thrown after attempting to apply a filter on a grid sourced from a parameterized report definition. This was traced to work done to allow cross-scripting filters to allow filters to contain special characters, and has been resolved.

Large filter values accepted in Report Definition edit
Resolved in Pega Version 8.2.8
Report definition edit filter values were not accepting large comma separated values properly. This has been resolved by modifying the logic in RRFilters_Logic to use ReportFilter.getReportFilters.

Scheduled tasks landing page shows all tasks
Resolved in Pega Version 8.2.8
Due to pzGetScheduledTasks listview having a hardcoded limitation of 500 records to be fetched, not all scheduled tasks were being shown in the scheduled tasks landing page. This has been resolved by modifying the pyCreateSummary activity to use a newly created Report Definition to fetch data instead of list view.
