  • PIVOT-4912 Add default implementation of CancellableCountedCompleter#afterCompute(Throwable) calling CancellableCountedCompleter#tryComplete().
  • PIVOT-4947 Return a lighter ActivePivot description in SOAP webservices called SoapActivePivotDiscovery.
  • PIVOT-4959 Reorganize the IVectorBinding API. Some methods have seen their two IVector parameters inverted, but they now all carry the less confusing names of left and right (rather than source and destination). The left vector will always receive the result of the vector operation.
  • PIVOT-4973 IReadableDatastore now implements IBranchedMultiVersion.
  • PIVOT-5003 Reorganize AMultiVersionAnalysisHierarchy and AAnalysisHierarchy to clearly state the methods to implement.

  • PIVOT-4244 Remove the XML descriptions of the cubes.
  • PIVOT-4747 ISelectionField was removed. Use SelectionField instead.
  • PIVOT-4748 StreamUtil.negate has been removed; we use Predicate.not instead
  • PIVOT-4776 IMultiMap was removed. Use a Map whose values are collections instead.
  • PIVOT-4986 Release more resources after dropping a partition (dictionaries of indexes that are not used by a reference can now be released every time).

  • PIVOT-5117 Remove TransactionWrapper.

​
Fixed

  • PIVOT-4487 Fix Copper post-processor bug where if the only underlying measures of a calculated measure were null or constant measures, the post-processor wouldn’t be evaluated at all.
  • PIVOT-4735 Fix continuous handler registration issue. The issue happened in distribution when some underlying measures have not yet appeared thus causing a duplication in handler key of the parent measure.
  • PIVOT-4780 Fix unnecessary query plan logging when queryPlanSummary is enabled.
  • PIVOT-4800 Enhance query plan timing reports. This particularly fixes two man issues:
    • JITPrimitiveAggregatesRetrieval Partitioned retrievals for non-existing partitions used to display the largest execution time of their siblings. Now, only partitioned retrievals that performed some work at least and whose result is empty will be reported in the timing section, along with the other retrievals with result
    • In some cases, for a group of related retrievals (siblings), timing were not printed if one of the sibling has no result. This edge case has been fixed
  • PIVOT-4811 Fix ClassCastException in SingleValueFunction when working with arrays.
  • PIVOT-4814 Fix an issue where exporting the memory statistic of a chunk containing non-direct vector blocks would throw a NPE.
  • PIVOT-4816 Fix an issue occurring when merging two AggregateStores. This caused the merged result to include null values instead of the correct value for some measures.
  • PIVOT-4818 Fix an issue leading to incorrect transitions between IntegerArrayVersion.
  • PIVOT-4819 Fix UnsupportedOperationException in ActivePivotStatistics. The issue happened when computing transaction fact statistics on an incompatible type of transaction.
  • PIVOT-4862 Fix an export error in the IMemoryStatistic generation for TombStone classes.
  • PIVOT-4866 Fix NullPointerException in FilterTranslator. The issue could happen when translating a wildcard, e.g. null, to the data cube.
  • PIVOT-4881 Fix an issue where the resizing of IntegerArray and LongArray generated non-transient chunks regardless of its isTransient parameter.
  • PIVOT-4901 Prevent aggregates computation (i.e. GetAggregatesQuery) when mdx CELL PROPERTIES is equal to CELL_ORDINAL.
  • PIVOT-4923 Fix hiding subtotals issue that could not hide all the measures.
  • PIVOT-4935 Fix NPE when accessing an uninitialized datastore via MBean.
  • PIVOT-4944 Fix the cleaning method of the prefetch scope location when executing more than one aggregation procedure in a single PrimitiveAnalysisAggregationRetrieval.
  • PIVOT-4946 Fix an issue with Copper storeLookup that could fail to find its underlying measures, in the case where these measures were previously re-optimized.
  • PIVOT-4949 Fix thread safety for SharedDelegateDictionary#mapFromCell.
  • PIVOT-4951 Fix an edge case issue with IChunkInteger sparse compression.
  • PIVOT-4956 Fix GenericVectorBinding#applyAs.. operations for non-commutative operators.
  • PIVOT-4958 Fix the update of the ContentServer entries for branches containing characters that are illegal for FileSystem-specific paths.
  • PIVOT-4964 Fix an ArrayIndexOutOfBoundException happening when compressing chunks with freed rows as FrequentValueChunk.

  • PIVOT-4979 Fix missing fields issue in the analysis aggregation procedures when a cube filter is done on a Copper join.
  • PIVOT-4992 Fix dependency issue in content-server-spring.
  • PIVOT-4998 Reduce time spent at startup optimizing Copper measures
  • PIVOT-5010 Properly set the level type of a slicing Copper hierarchy
  • PIVOT-5016 Fix ArrayIndexOutOfBoundsException in the SetExpander of the Mdx engine.
  • PIVOT-5038 Fixed errors in usage counting caused by decrementing the usage too many times.
  • PIVOT-5050 Fix distributed post-processors initialization. This issue happened when chaining at least three post-processors where the bottom one in the chain is not initialized and caused missing dependencies propagation in some cases.
  • PIVOT-5062 Fix NullPointerException in PointListRetrievalResult in the case of a polymorphic distributed setup.
  • PIVOT-5068 Fix NullPointerException in the AggregatesResultCopier used by postprocessors.
  • PIVOT-5074 Fix SubCubeProperties#removeRestriction(dimension, hierarchy). The issue happened in distributed polymorphic setup where the same dimension from two data nodes includes different hierarchies and one of the dimension hierarchies cardinality is greater than 1.
  • PIVOT-5078 The Parquet Source correctly parses boolean vectors.
  • PIVOT-5097 Fix NullPointerException when registering a GetAggregatesQuery build using a location Collections not supporting null elements.
  • PIVOT-5115 Fix IllegalArgumentException during query plan logging when executionTimingPrint is enabled.
  • PIVOT-5119 Fix rollback process of store transactions.
  • PIVOT-5128 Fix a memory leak that could happen upon query failure/cancellation if an AggregatesCache was used.
  • PIVOT-5137 Fix LevelIdentifier.fromDescription and HierarchyIdentifier.fromDescription. They did not handle correctly the escaping of @.
  • PIVOT-5151 Fix QfsStrings.escape with $ as escape symbol.
  • PIVOT-5156 Fixed missing query plan retrievals. The issue happened when underlying retrievals with different partitioning were merged. Note that this does not affect query results nor the query plan export feature, but only the query plan printing.
  • PIVOT-5162 Fix potential NPE in PrimitiveAnalysisAggregationRetrieval when joining results.
