5.9.8

2021-05-28

Added

• PIVOT-4638 Add the maskAtOrBelow() method to the CopperMeasureToAggregateAbove interface, allowing to define levels below which a measure will not return aggregated values when queried. The behavior is the complementary of the doNotAggregateAbove() method.
• PIVOT-4806 License path is now printed in the log.

Changed

• PIVOT-4781 StreamSnapshotService#snapShotStreams(String) is now compatible with StreamSnapshotService#loadStreams(String). Now, both operation ignore STOPPED streams. Use StreamSnapshotService#snapShotAllStreams(String) to snapshot all streams including the stopped ones.
• PIVOT-4789 Provide possible solutions in error message when we failed to initialize the SaferNative class in LinuxPlatform.
• PIVOT-4802 Reduce the memory consumption of ModifiedLocation, primarily used in cumulated aggregates and in shifted measures.

Fixed

• PIVOT-4749 Clarify the documentation of the cube/export/mdx/download REST service endpoint.

5.9.7

2021-04-26

Added

• PIVOT-4491 Add support for primitive aggregated measures in the Aggregates Cache.
• PIVOT-4702 Add support for DATEPART function in MDX with the simple signature DatePart(interval, date).
• PIVOT-4713 Add the method IDistributedHierarchyManager#waitForAllMessages allowing to wait for all the recorded messages to be processed.

Changed

• PIVOT-4300 Post-processor dependency graph cycle detection is now enabled by default.
• PIVOT-4780 Change MBeans in QueryPlanMonitoring to print execution plan and timing full or as summary, e.g. QueryPlanMonitoring#enableExecutionTimingPrintFull() or QueryPlanMonitoring#enableExecutionTimingPrintAsSummary().

Fixed

• PIVOT-3790 Fix the partitioning levels of the legacy post-processor NeighbourValuePostProcessor.
• PIVOT-4344 Fix SingleValueFunction on Arrays type.
• PIVOT-4364 Fix Real-Time issues with Copper. This includes the following corrections:
  • In addition to the CommitIsolatedStoreHandler handler, join measures now include the StoreMeasureHandler in their handlers' list
  • Copper#newPostProcessor(..) allows now to propagate the underlying measures handlers using CopperPostProcessor#withInheritedContinuousQueryHandlers()
  • Delegate continuous handler initialization to post-processors
• PIVOT-4443 Fix an edge case in chunk compression where a chunk entirely filled with Integer.MIN_VALUE or Long.MIN_VALUE would not be compressed into an IChunkSingleValue.
• PIVOT-4489 Fix issue with branch permission manager preventing to see new branches on real time Mdx queries.
• PIVOT-4525 CopperMeasure#parentValueOn(CopperHierarchy) now properly handles an analysis hierarchy being passed as an argument.
• PIVOT-4593 Fix a bug where the batched parquet parser would read incorrect values for all subsequent vectors if a column contained a null or empty vector.
• PIVOT-4678 Fix a bug where similar Copper measures using different constants were confused with each other.
• PIVOT-4691 Fix possible casting exception when using CopperMeasure#withType(ILiteralType.BOOLEAN) with an aggregation function returning Boolean.
• PIVOT-4716 Mdx Median function now regularly checks for query interruption.
• PIVOT-4719 Fix lazy initialization and double check idiom in RecordFormat#getFieldIndex(String).
• PIVOT-4725 Some datastore versions were not unmarked after stopping the cubes.
• PIVOT-4728 Measure names with several parentheses were not correctly supported by the Formula PostProcessor.
• PIVOT-4730 Prevent Real-Time statistics errors from crashing continuous queries update. The issue happened when statistics computations tried to fetch retrievals that had been dismissed by the query engine (usually because of a non-existent location).
• PIVOT-4739 Fix publishing of WindowReduceMeasure (description equality).
• PIVOT-4760 Fix an issue where IStoreToParquetMapping would map fields from the datastore to the wrong fields in the parquet schema.
• PIVOT-4771 Fix NPE cause by CopperPostProcessor#withInheritedContinuousQueryHandlers. The issue happened while inheriting the handlers of a post-processor that hasn't any.
• PIVOT-4772 Fix a query issue where wildcards on slicing analysis hierarchies based on isolated store fields would conflict with Copper bucketing hierarchies.
• PIVOT-4814 Fix an issue where exporting the memory statistic of a chunk containing non-direct vector blocks would throw a NPE.

Security

• APS-12594 BREAKING The XML parsers used throughout ActivePivot (JAXB, XMLA Servlet...) are now given a restrictive configuration to better prevent XXE injection attacks:
  • Automatic DDoS prevention. This may limit XML constructs, such as deep recursive XML elements (XML entities calling more XML entities, and so on).
  • Disables !DOCTYPE annotation to prevent XXE injections through this annotation.
  • Disables the XInclude annotation to prevent construction of sub-documents that could be retrieved from a distant server.
  • Disables the use of external Document Type Definitions, for the same reason.

5.9.6

2021-02-12

Added

• PIVOT-4490 Add health events to the JDBC source notifying the success or the failure of a JDBC source fetch. These health events can be handled using the interface IJdbcSourceHealthEventHandler.

Changed

• PIVOT-4558 Change the behavior of IHierarchy#isEmpty(). Now, the method checks whether the corresponding hierarchy is empty or not instead of checking for leaf members. This enhances the performance of queries with high cardinality hierarchies.
• PIVOT-4589 Add support in the parquet source for filtering parsed files using a java.util.regex.Pattern, through IParquetParserBuilder.withPattern(java.util.regex.Pattern).
• PIVOT-4590 Fix ArrayIndexOutOfBoundsException occuring when merging two retrieval results. Particularly, the issue was due to the fact that some post-processors ignore null values and don't write them into the final result. As a consequence, the capacity of the underlying post-processor column won't be aligned with the retrievals points, causing such exception when merging the actual result with another one.
• PIVOT-4620 Fix issue with Hibernate where a high number of input parameters causes server exceptions.
• PIVOT-4622 Fix ActiveMonitor PointValue commit logic. This adds a consistency check when committing an update on an existing point value. Now, we make sure that the "from" point value and its active value in the database have the same key. Otherwise, the commit is not allowed and an exception is thrown.

Removed

• PIVOT-4615 Remove heavy-to-compute logging in ImpactComputationTask.

Fixed

• PIVOT-3352 Add fencing on APrimaryRecordTransaction methods.
• PIVOT-4241 Fix the reserved memory tracking of the SlabMemoryAllocator when the cache is evicted.
• PIVOT-4503 Fix a bug where the batched parquet parser would not properly read row group and page metadata, potentially throwing an end-of-file exception.
• PIVOT-4507 Fix issue with mdx drillthrough query involving a member whose name contains brackets
• PIVOT-4533 Fix a bug in Copper where an UnsupportedOperationException would be thrown when subtracting a float, long, or int vector to a null vector aggregate.
• PIVOT-4534 Prevent PrimitiveAnalysisAggregationRetrieval from inheriting not required measures from its underlying retrieval. This prevents mismatch binding when a parent PrimitiveAnalysisAggregationRetrieval depends on a child PrimitiveAnalysisAggregationRetrieval including additional join measures. It also improves the query times and memory usage for such cases.
• PIVOT-4542 Improve error message when QueriesResultLimits are exceeded.
• PIVOT-4563 Fix a bug where the Left and Right MDX functions would throw a NullPointerException for null values.
• PIVOT-4564 Levels from hidden dimensions and hierarchies are now omitted in XMLA discoveries. This caused an incompatibility with some XMLA clients such as ADOMD.NET.
• PIVOT-4565 Fix a bug where enforcing a parallel computation of a Copper join could make a query timeout.
• PIVOT-4572 Fix ClassCastException during the execution of MDX queries relying on previously cached aggregates. The issue is due to a bad partitioning of a post-processor depending on a cached node and a non-partitioned post-processor node. Now, cached nodes forbid all partitioning levels and buble them up to their respective parents.
• PIVOT-4586 Fix NullPointerException in DriltthoughResultDTO.
• PIVOT-4592 Fix Copper errors when reusing code to build complex measures.
• PIVOT-4626 Fix a bug in the parquet source where an invalid index exception would be thrown if a parquet vector field was not mapped to any field in the fed datastore.
• PIVOT-4633 Fix ClassCastException in DataCubeAdapter.
• PIVOT-4671 The Query cube will now always reject messages and contributions from unknown applications.

5.9.5

2020-12-17

Added

• APS-12943 Allow -1 value for a limit to signify no-limit on QueriesResultLimit context value.

Changed

• APS-12946 Enhance versions management in distribution. Versions are now handled using a dedicated DistributedEpochManager that keeps track of versions history and trigger discard tasks on GC. The DistributedEpochManager is visible in the Manager MBean under the corresponding distributed cube MBean.
• APS-12975 Reduce DiscardOnGcTask timeout duration from one hour to one minute. In very rare cases, this will let a version be discarded more rapidly after being released.
• PIVOT-3914 Change AAdvancedPostProcessor.computeOutputType() to fall back to the return type of its evaluator, if it has one.
• PIVOT-4438 Update MDX engine error messages to use hierarchy unique names instead of simple names.
• PIVOT-4509 Register standard Drillthrough calculators through an extended plugin.
• PIVOT-4522 BREAKING: Change the signature to create a UDAF to allow allocating vectors off-heap and lazy cloning. One should now call IWritableBuffer.allocateVector instead of IVector.cloneOnHeap(), and IWritableBuffer.readWritableVector(int) instead of IWritableArray.readVector(int).
• PIVOT-4579 The severity of the log message notifying that a property is missing has been changed from WARNING to INFO.

Deprecated

• PIVOT-4428 Deprecate following methods:
  • IChunk.findRowsInTransactionEqualTo(Object, IIntIterator, int, IRowMapping, int, IBitmap)
  • IChunkSet.findRowsInTransactionEqualTo(int, Object, IIntIterator, int, int, IBitmap)
  • IChunk.findRowsInTransactionInSet(Set, IIntIterator, int, IRowMapping, int, IBitmap)
  • IChunkSet.findRowsInTransactionInSet(int, Set, IIntIterator, int, int, IBitmap) as duplicates of their counterpart outside of a transaction (findRowsEqualTo, ...)

Fixed

• APS-12937 All measures impacted by a full refresh will now be included in the FullRefreshEvent. Some of them might have a null value.
• APS-12962 Fix bug preventing measure publication when using withType(...) on a calculated measure, and reusing this measure in another calculated measure.
• APS-12965 Fix Copper Join producing incorrect aggregation results when using a Join Measure based on the key fields of the joined Store.
• APS-12966 Fix an issue where formatters would not be taken into account for UDAF measures.
• APS-12985 Correct overflow error in dictionaries occurring when inserted more than 2 ^ 30 values in a field dictionary.
• PIVOT-4370 The Parquet Source now correctly handles empty strings when writing into a store field that should not support empty strings, replacing them with the store field's default value.
• PIVOT-4455 Correctly compute vector average, ignoring null vectors instead of counting them as actual values.
• PIVOT-4457 PIVOT-4457 Correct Datastore conditions testing for equality or greater-than/less-than on nullable fields. Previously, this could:
  • throw an exception for a non-dictionarized field with long series of null values;
  • return incorrect rows from the store when looking for the primitive value 0 on a non-dictionarized field;
  • return rows with null for greater-than/less-than conditions.
• PIVOT-4460 Fix a bug where MemoryAnalysisService would not produce report files for query cubes in distributed application.
• PIVOT-4461 Fix NullPointerException during Datastore queries looking for null in store fields after compression. This only happened in the case of offset compression, for int and long values or dictionarized fields.
• PIVOT-4500 Fix filter translation edge case in distribution. This caused AND filtering operation on the same hierarchy to be wrongfully translated into an OR operation.
• PIVOT-4503 Fix a bug where the batched parquet parser could throw an end-of-file exception when reading a vector column.
• PIVOT-4517 Fix a bug where an ArrayIndexOutOfBoundsException would be thrown when generating the memory statistic of an empty target store referenced by a non-empty owner store.
• PIVOT-4516 UDAF used in a aggregate provider always stored its vectors on heap.
• PIVOT-4527 Fix XMLA discovery of UDAF measures.
• PIVOT-4532 Fix the computation of retrieval results size in the query plan. The total result size for partitioned retrievals were not accumulated together correctly and an empty result for a partition was causing a NPE.

5.9.4

2020-11-06

Added

• APS-12558 Add new MdxContext parameters that can override the visibility of hierarchies and dimensions, forcing them to be shown or hidden regardless of the cube's configuration.
• APS-12879 Add a new property to activate Copper checks that will be added in 5.10 (activeviam.copper.measure.enforceName=true). Expressions like Copper.sum("pnl").publish(context) will have to be replaced with Copper.sum("pnl").withName("pnl.SUM").publish(context) (one should not rely on default measure name).
• APS-12908 Add a selectDistinct() method to DatastoreQueryHelper that accepts a condition.
• PIVOT-4409 Allow to define an Analysis hierarchy on the base store (withStoreName method)
• PIVOT-4417 Add a new compression for chunks, storing only values different from a frequent value.

Changed

• APS-12918 Add more parser-policy-related interruption checks to the CSV source's ParserTasks. This can considerably improve performance when using the sampling parser policy.
• APS-12932 Bitmap operations now catch CancellationException early to prevent logging bitmaps that are valid.
• APS-12788 AxisHierarchy now reports that a field used to create a level should be dictionarized, instead of stating that this operation is only available in unit-tests.

• APS-12915 Correctly process Cube Filters in a distributed application.
• APS-12931 Fix an erroneous check that would throw when trying to define user-defined aggregate functions in partial aggregate providers.
• PIVOT-4370 The Parquet Source now correctly handles empty strings when writing into a store field that should not support empty strings, replacing them with the store field's default value.
• PIVOT-4388 Changed the return type of the Store Builder method withVectorField when chained after a dictionarized or indexed vector field. It gives access to a much fuller API to configure this second vector field, or finish configuring the store with methods like withoutKey().
• PIVOT-4427 Fix ChunkedBitmap#equals implementation.
• PIVOT-4436 Fix ClassCastException occurring when a join measure was defined on a dictionarized field.

5.9.3

2020-09-29

Added

• PIVOT-4191 Limit intermediate and transient retrievals result size within a GetAggregatesQuery using QueriesResultLimit. Intermediate result size referes to the size of a single retrieval whereas the transient result size is the result size cross retrievals belonging to a single GetAggregatesQuery. Note that this limit is set with respect to the number of points i.e. retrieval locations.
• PIVOT-4341 Add IArrayReader.readVector method.
• PIVOT-4387 Add a validation step for StoreToParquetMappings before parsing a parquet file.

Changed

• APS-12854 Important: Remove Where operation now throws if the given condition reads in or through a store locked in the transaction (a store which will be written into concurrently).
• APS-12878 Improve the optimization of copper measures depending on other copper measures. In some cases the number of intermediary results will be reduced: this will reduce the memory consumed by queries.
• PIVOT-4391 Memory statistic exports do not include chunks of records for future versions anymore.

Deprecated

• APS-12854 deprecated SchemaHelper methods followReferences and getStoresInReferencesPath. The class now has methods with specific implementations whether the path given ends with a field name or not.

Fixed

• APS-12731 Fix QueriesTimeLimit heuristic overflow in the MDX engine. This led to cases where the actual query was still running, yet because of the overflow, the query engine was continuously timing out, creating erroneous TimeoutExceptions that never bubbled up because the query didn't time out.
• APS-12861 Fix the planning of ExternalDatastoreRetrieval to remove duplicate retrieval executions.
• APS-12863 Fix UnsupportedOperationException occurring when applying branch security in BranchUtils.grantBranch. It happened when the SubCube Properties of the current user were an intersection.
• APS-12871 Fix an edge-case issue with the RemoteContentServer that would throw if two paths in the Content Server were equal up to a / in the first, and a special character in the second.
• APS-12873 Fix a bug in LocationBuilder#setCoordinate(). The method was skiping levels during path iteration.
• APS-12876 Fix an NPE occurring with history aggregation functions in the case of a Copper Inner Join with no matching facts in joined store.
• APS-12885 Fix an edge-case where datastore query yields additional unexpected results. The issue happens when specifying a condition on a reference field and the target store includes a ValuePartitioning on that field.
• APS-12889 Fix a wrong error message displayed when attempting to perform arithmetic operations between measures with incompatible types in Copper.
• PIVOT-4383 Fix faulty behavior in MemoryAnalysisService regarding the exporting of multi-versioned datastores.
• APS-12891 Fix potential ClassCastException when using the square sum or multiply aggregation function on int values.
• PIVOT-4382 Fix a bug where MemoryAnalysisService's Dump memory statistics for some epochs bean operation would produce statistics that were incompatible with MAC.
• PIVOT-4384 Fix a bug where calling AConcreteReferenceVersion::getMemoryStatistic() on a reference version whose owner or target partition was dropped in a subsequent epoch would produce a NullPointerException.
• PIVOT-4392 Improve the performance of the batched parquet parser on binary fields.
• PIVOT-4400 Support compiling ActivePivot projects with recent JDKs.
• PIVOT-4401 Fix a bug in the completion of JIT retrievals that could lead to threads not being properly stopped when encountering an exception in underlying retrieval operations.

5.9.2

2020-08-14

Added

• APS-12708 Add a new method CopperMeasure.marginalTotalOn(hierarchies...) to the Copper API to create marginal totals over an existing measure. Added CopperMeasure.totalOn(hierarchies...) and CopperMeasure.grandTotal().
• APS-12724 Add a new ActiveViamProperty, set through -Dactiveviam.contentServer.restrictedListing=<boolean>, which will change the permission behavior of the Content Server. It defaults to false. When set to true, a user will not be able to list a file without having read access to the said file, even if he has read access to the parent directory.
• PIVOT-4304 Add indexed aggregate providers support for user-defined aggregate functions.
• PIVOT-4342 Add automatic support for String vectors in the parquet source.
• PIVOT-4355 Add IBroadcastMessage#getMessageClass() and IBroadcastResult#getAnswerClass() methods allowing to retrieve respectively the class representing a message type and an answer type.
• PIVOT-4324 Add IParquetParserBuilder to build parquet source parsers. Add a new parquet parser implementation that reads records in batches, leading to significant performance improvements.
• PIVOT-4354 Add JUnit5 extensions equivalent of test rules JUnitCubeTesterBuilder, DistributedRule, ResourceRule and ActiveViamPropertyRule. Migrate ATestFencing to be JUnit 5-compliant.
• DOC-273 Add a new property activeviam.i18nconfig.file.encoding, used by LocalI18nConfig to control which encoding to decode internationalization files with.

Changed

• APS-12730 Improve query engine to keep the maximal partitioning for operations on primitive measures.
• PIVOT-4233 Performing a filtering operation with an OR condition is now only possible in Copper if both operands are on the same level.
• PIVOT-4324 Parquet source parsers should now be constructed using a IParquetParserBuilder.
• PIVOT-4371 Improve the performance of BasicPostProcessor evaluation.
• DOC-273 Simplify LocalI18nConfig to avoid needing to use the content service, and instead use local resource files directly for internationalization.

Deprecated

• APS-12805 The Mdx engine now supports VBA functions used with the VBA! prefix.
• APS-12823 Fix Sandbox CORS configuration.
• PIVOT-4233 Performing a filtering operation with conditions on multiple levels of the same hierarchy now performs an AND operation for each filtered level.

• PIVOT-4326 Fix Copper Window functions interaction with the QueryCache.
• PIVOT-4363 Fix a memory leak caused by User-Defined Aggregate Functions when running queries.

5.9.1

2020-06-25

Added

• APS-12715 IPostProcessedRetrievalResultWriter.aggregateAndContribute(IAggregationFunction, int, List<? extends IIterableAggregatesRetrievalResult>). The extra argument provides the type of data consumed by the aggregation function. While this type is often the same as the measure type, functions converting longs to vectors of longs break this assumption.
• APS-12740 Add support for a flexible ISecurityWebSocketHandlerFactory allowing to override the default SecurityContextWebSocketHandle handler.

Changed

• APS-12753 Throw a clearer intermediate exception if an exception occurs during row parsing, when feeding rows to a datastore through DatastoreService.
• APS-12757 Reducing network call of ICloudEntityPath#getLastModified() for Azure implementation.

Deprecated

• APS-12715 Deprecating IPostProcessedRetrievalResultWriter.aggregateAndContribute(IAggregationFunction, List<? extends IIterableAggregatesRetrievalResult>) to replace it with IPostProcessedRetrievalResultWriter.aggregateAndContribute(IAggregationFunction, int, List<? extends IIterableAggregatesRetrievalResult>).
• APS-12718 Deprecating DrillthroughExecutor.doExecuteHeaders(Collection<ILocation> locations, Collection<String> measures, boolean isDrillthroughContinuousQuery, boolean log) in favor of its overloaded sibling without the log boolean. For removal in 5.10.0.

Fixed

• APS-12080 Fix Content Service MBean registration.
• APS-12588 Fix a bug with dropped partitions. The drop was not correctly reverted when the transaction was rolled back. This could cause multiple exceptions in the Bitmap aggregate provider.
• APS-12656 Fix a bug that could occur when downloading large files from Azure.

• APS-12752 Fix PrimaryIndexRangeLookup for datastore query on non-existent member.
• APS-12763 Fix a bug in GetAggregatesStream, causing UnsupportedOperationExceptions.
• PIVOT-4307 Mismatches for an aggregation procedure now only impact the join measures of said procedure, and a mismatch on a procedure will no longer lead to the failure of the following aggregation procedures on the same location.
• PIVOT-4309 Correct the health messages for distribution.
• PIVOT-4310 Records the actual start time for DistributedPostProcessedRetrieval instead of using the start time of the underlying task.

• ABasicPostProcessor (respectively ABaseDynamicPostProcessors) now uses named prefetchers. They will use the constant ABasicPostProcessor.BASIC_POST_PROCESSOR_PREFETCHER (resp. ABaseDynamicAggregationPostProcessor.DYNAMIC_AGGREGATION_POST_PROCESSOR_PREFETCHER) as the name of the prefetcher to retrieve. If you define your own prefetcher you need to name it correctly :

IPrefetcher<?> namedPrefetcher = IPrefetcher.name(ABasicPostProcessor.BASIC_POST_PROCESSOR_PREFETCHER, prefetcher);

• APS-11227 The driverClassName argument for the JDBCSource constructor has been moved to SimpleConnectionSupplier. It is now only required when no IConnectionSupplier is provided.

The new ICubeFilterBuilder.includeMembers now only accepts List<String> The ICubeFilterBuilder.excludeMembers method accepting wildcards for members path name (eg. List<?>) has been moved to excludeMembersWithConditions. The new ICubeFilterBuilder.excludeMembers now only accepts List<String>

• PIVOT-3670 When a listener listening on several branches (e.g. pivot) is attached on a non empty datastore, it will now catch up with the current state in a maintenance operation (i.e. blocking all transactions until it catches up).

  For listeners listening on a single branch, the catch-up mechanism was improved. As previously, it does not block transactions, but its memory footprint was improved. The property qfs.selection.listener.catchUpMaxTime defines the maximum time (in s) in which the listener will try to catch-up while not blocking transactions: when it is exceeded, the listener will run a maintenance operation to finish catching up. The default value is 3min, and setting a non positive duration sets an infinite maximum time.

• APS-10813 Fix legacy post processor visibility
• APS-10881 Analysis hierarchies were only partially supported by basic and dynamic post processors. The analysis levels were removed on the location but not the cube filter. As fixing this behavior might introduce breaking changes in how the post processors work we introduced three new classes that must be extended instead of the previous version if the post processor uses the analysisLevels property:
  • ABasicPostProcessorV2
  • ABaseDynamicAggregationPostProcessorV2
  • ADynamicAggregationPostProcessorV2 These classes will be merged back into there classic implementation in 5.8, potentially introducing a breaking change for subclasses that overwrite the compute function or the prefetchers Post Processors that try to use analysisLevels without handling it correctly will now log a warning during the init. You can learn how to correctly implement AAdvancedPostProcessor with analysis levels in this confluence article.

• PIVOT-3675 Default implementations exist to configure branch and store permissions. They are designed for development, not apply any security.
  See FullAccessBranchPermissionsManagerConfig and NoSecurityDatastoreServiceConfig.

This store is now partitioned by parameter name and ActivePivot name for which it defined, so any lookup for a given parameter within a given cube hits a given partition. Then, the partitioning distributes the point values on a multi-modulo of the erasure and the wildcard erasure using the number of cores of the machine.
• APS-10426 Null values in parquet source are now converted to default field value.

Fixed

• APS-10614 Correct query planning for query cubes with respect to analysis hierarchies.
