Changelog

The format is based on Keep a Changelog and this project adheres to Romantic Versioning.

5.7.19

2021-05-27

Changed

  • PIVOT-4789 Provide possible solutions in error message when we failed to initialize the SaferNative class in LinuxPlatform.

Fixed

  • PIVOT-4811 Fix ClassCastException in SingleValueFunction when working with arrays.
  • PIVOT-4819 Fix UnsupportedOperationException in ActivePivotStatistics. The issue happened when computing transaction fact statistics on an incompatible type of transaction.

5.7.18

2021-04-28

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.
  • PIVOT-4480 Add a JMX operation in the store monitoring MBean that produces a general chunk memory usage report.

Changed

  • PIVOT-4620 Replace Hibernate CriteriaBuilder#in() by Hibernate InPredicate. This solves cases where a high number of input parameters causes server exceptions.

Fixed

  • APS-13016 Better handle network errors which were causing issues with license checks.
  • PIVOT-4344 Fix SingleValueFunction on Arrays type.
  • 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-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-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.
  • 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-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).

5.7.17

2021-01-21

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.

Fixed

  • PIVOT-3352 Add fencing on APrimaryRecordTransaction methods.
  • PIVOT-4241 Fix the reserved memory tracking of the SlabMemoryAllocator when the cache is evicted.
  • PIVOT-4507 Fix issue with mdx drillthrough query involving a member whose name contains brackets
  • PIVOT-4563 Fix a bug where the Left and Right MDX functions would throw a NullPointerException for null values.
  • 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 Properly set the max message sizes for NettyMessenger messages in distribution, and generate a comprehensive exception message when exceeding such limits.
  • PIVOT-4586 Fix NullPointerException in DriltthoughResultDTO.
  • PIVOT-4586 In some cases the server could send a transient empty drillthrough result when the actual result was computed. This is no more the case.

5.7.16

2020-12-21

Changed

  • 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-4438 Update MDX engine error messages to use hierarchy unique names instead of simple names.

Fixed

  • 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-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-4551 Fix ArrayIndexOutOfBoundException during the streaming of a MDX query with no ranges added to it.
  • 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.
  • APS-12985 Correct overflow error in dictionaries occurring when inserted more than 2 ^ 30 values in a field dictionary.

5.7.15

2020-11-16

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.
  • PIVOT-4387 Add a validation step for StoreToParquetMappings before parsing a parquet file.
  • PIVOT-4713 Add the method IDistributedHierarchyManager#waitForAllMessages allowing to wait for all the recorded messages to be processed.

Changed

  • APS-12715 Deprecating IPostProcessedRetrievalResultWriter.aggregateAndContribute(IAggregationFunction, List<? extends IIterableAggregatesRetrievalResult>) to replace it with IPostProcessedRetrievalResultWriter.aggregateAndContribute(IAggregationFunction, int, List<? extends IIterableAggregatesRetrievalResult>).
  • 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-12932 Bitmap operations now catch CancellationException early to prevent logging bitmaps that are valid.

Deprecated

  • APS-12715 Deprecating IPostProcessedRetrievalResultWriter.aggregateAndContribute(IAggregationFunction, List<? extends IIterableAggregatesRetrievalResult>) to replace it with IPostProcessedRetrievalResultWriter.aggregateAndContribute(IAggregationFunction, int, List<? extends IIterableAggregatesRetrievalResult>).

Fixed

  • APS-12641 Fix ranges update on registered query.
  • 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-12769 Prevent NPE in AAdvancedPostProcessor#retrieveNamedPrefetchAggregatesWithAnalysisLevels
  • APS-12871 fixed 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-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-12952 Fix sanity-check in ActiveMonitor alert system, not preventing for dispatching incorrect events.
  • 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-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.

5.7.14

2020-07-09

Added

  • APS-12724 Add a new System Property, 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.

Fixed

  • APS-12300 Fix a bug affecting the ContentServer cached entries that were invalidated even when not necessary.
  • APS-12739 Fix a bug affecting branches for distribution, where hierarchies could be seen as not empty even if they were.
  • APS-12763 Fix a bug in GetAggregatesStream, causing UnsupportedOperationExceptions.
  • APS-12777 Allow StreamingService to garbage collect and dispose of already stopped streams.

5.7.13

2020-06-04

Added

  • APS-12511 The ActivePivot Version of the project is now printed at project initialization, and is accessible through the ActivePivot Manager MBean.

Changed

  • APS-12514 Changing the default companion when the expression of the calculated member is a member of the same hierarchy and not a calculated member. This will improve the performances.

Fixed

  • APS-12546 CSVSourceConfiguration constructor correctly uses the defaults of the given Properties, if present.
  • APS-12549 Fix postprocessors auto-partitioning in the the finalization of planning phase.
  • 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-12700 Fix IndexOutOfBoundsException appearing randomly when using rangesharing. The computation was failing in presence of factless locations.
  • PIVOT-4288 Fix query planning producing wrong aggregated values when the datastore is partitioned on a field absent in the pivot.
  • PIVOT-4321 It was not possible to change the Aggregate Cache's size at runtime, if the cache was disabled in the description.

5.7.12

2020-02-14

Changed

  • APS-11967 BREAKING: consider the cube filter when replicating results from Data Cubes. Like with locations, if the Cube Filter contains hierarchies absent from the Data Cube, replication won't apply, according to the distribution property dataReplication.
    Not to break existing projects, a temporary new replication policy was introduced REPLICATE_ON_SLICER_IGNORING_FILTER. It provides the behaviour before the fix, and will be removed in 5.9.
  • APS-12304 BREAKING: Adding a check for partial provider measures that verifies that the included/excluded measures are valid aggregated measures. Any project not respecting this constraint will throw a QuartetRunitimeException at start-up.
  • APS-12458 Fix a StreamCorruptedError that could happen in NettyInputStream after receiving an exception message, and wrongly resetting the stream's reading index.

Deprecated

  • APS-11967 The following were only defined for support reasons and are already deprecated.
    • Enum value DataReplication#REPLICATE_ON_SLICER_IGNORING_FILTER
    • Value "REPLICATE_ON_SLICER_IGNORING_FILTER" for the Distribution property dataReplication.
  • APS-12215 Internal methods potentially visible to users have been deprecated:
    • IInternalAggregatesRetrievalResult#join(..) without ICubeFilter
    • IInternalAggregatesRetrievalResult#expandResult(List<? extends IHierarchy>, List<? extends ILevelInfo>)

Fixed

  • APS-11728 Fix a bug in the QFSBitmap.not operator, that could produce malformed bitmaps that could make other operations throw when run on the malformed bitmap.
  • APS-12175 Fix bug in the Mdx Iif function when used with tuples
  • APS-12215 Correctly set retrieval results filters when Analysis Hierarchies are involved. It previously resulted in missing results.
  • APS-12227 Fixed JSON queries that wrongly locked all stores
  • APS-12306 Fix an UnsupportedOperationException occurring when committing on a branch after dropping and recreating a partition on another branch. Also fix disappearing records on a branch when, on another branch, their partition is dropped and not re-created.
  • APS-12305 Fixed an issue with branch deletion in a distributed cluster, causing a small memory leak for each deleted branch.
  • APS-12387 PointListRetrievalResult methods now regularly checks for query interruption, preventing certain queries to continue running in the background while they have responded with a timeout.
  • APS-12391 Fix a NullPointerException that occured when removing a data node and readding it to the cluster within removalDelay seconds.

5.7.11

2019-11-04

Changed

  • APS-10757 Improve ClientPool constructors to avoid confusion between properties and extensions. This correct usages of client pools to correctly pass the properties.
  • APS-10856 Fix an ArrayOutOfBoundsException when a new partition is created in the middle of a query planning
  • APS-10630 Queries on a query cube with an empty data cube no longer throw a NullPointerException.
  • APS-10929 Fix NullPointerException which sometimes happened when conflating transactions.
  • APS-10880 Fix NullPointerException when expanding query scope into a location associated with no facts.
  • 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-3737 Correct ConcurrentModificationException when using aggregation procedures.
  • PIVOT-3738 Correctly consider partitionings of underlying retrievals of aggregation procedures.

5.7.2

Added

Changed

  • APS-10627 The Epoch dimension is now visible by default when enabled.
  • PIVOT-3685 Detects usage of analysis hierarchies within the cube filters or the security subcubes.
  • APS-10691 Added QFSPools.getMixedWorkloadThreadCount() to allow knowing how many threads can be used at max for a transaction (or for a query, since transaction and query pools have the same size).
  • SENTINEL-624 Improve performance of the Repository during insertion of new point values and while computing differential updates involving a lot of deleted point values.
  • APS-10708 Fail when registering a workflow relying on an undefined Activiti workflow process.
  • PIVOT-3707 Cube filters are now available to AggregationProcedures from #createContext through the ActivePivot context.
  • APS-10615 It is now possible to exclude a specific field from the selection when adding all fields or all reachable fields of the base store or a reference (using .except()), rather than always excluding all fields with the same name (which is what .excluding() does)
  • PIVOT-3675 Default implementations exist to configure branch and store permissions. They are designed for development, not apply any security.
    See FullAccessBranchPermissionsManagerConfig and NoSecurityDatastoreServiceConfig.
  • APS-10711 Formatting for thousand/million rescaling and multisection formatting are now supported.
  • PIVOT-3224 Join between datasets now uses Analysis Aggregation Procedures.

Removed

  • The following classes have been removed from the sandbox:
    • ForexPostProcessor
    • ForexHandler
    • ForexStream
    • ReferenceCurrency
    • ReferenceCurrencyTranslator.
  • The measure pnl.FOREX is defined in copper. The currency can now be chosen via a new slicing hierarchy named TargetCurrency (automatically created by copper).

Fixed

  • APS-10699 Avoid exception when new branch is created without subcube
  • PIVOT-3699 A multimensional single element set in the MDX WHERE clause now works (like a tuple).
  • APS-10740 Correctly compute modulo on multiple fields, not to double the number of produced values.
  • APS-10766 unmark epochs that are released because they corresponded to shadow commits
  • PIVOT-3580 Implementation of a filtered list, FilteredList, to manage different measure description (sub)types for a single parent list.
  • PIVOT-3673 Fix NullPointerException when an ExpandLocationResult overflows during large transactions
  • APS-10724 Correct formatting of alert messages in the sandbox project.

5.7.1

Added

  • APS-6362 The Aggregate Store size was added in JMX for both the Bitmap and Leaf aggregate providers.
  • PIVOT-3548 The Content Server UI now has a title.

Changed

  • APS-10622 APS-10624 PIVOT-3608 Fluent Builder API was improved (slicing, factless, memberProperty).
  • SENTINEL-622 Improve the parameter store partitioning. 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.
  • APS-10184 Measures from different applications and with the same aggregation id (even if they have different names) are no longer merged in the the query cube, giving wrong results
  • APS-10591 Correct merging of retrieval results not containing any aggregated measures.
  • PIVOT-3537 Correctly update permissions of folders from the Content Server UI.
  • APS-10580 Prevent from automatically adding levels to analysis hierarchies declared using an xml file, and add check that analysis hierarchies do not have levels.
  • APS-10528 Fix MemberNamePathStyle context value in intersected context
  • APS-10545 Fix issue when a data cube leaves its cluster while planning a query
  • PIVOT-3224 (CoPPer) Use actual cube name in tests

5.7.0

Added

  • PIVOT-3612 Drop dedicated Angular UI of ActiveMonitor. ActiveUI becomes the only UI for this component, providing all features of the old UI. See the migration notes to see how to update your existing post-processors.
  • PIVOT-3609 Support prepared statements in fetch-only JDBC Topics
  • DS-293 Add API to create CompiledGetByKey query and run them, either on a particular version (runInVersion) or on the current transaction (runInTransaction). See the documentation for more details and examples.
  • PIVOT-3655 The Content Server / Service supports multiple owners and readers for each entry.
  • APS-10493 Create AFilteringPostProcessor to increase flexibility when implementing a filtering post-processor.

Changed

  • PIVOT-3584 Replace IPartitionedPostProcessor#getPartitioningLevels(...) called IPostProcessor#setPartitioningLevels(..) to configure the levels on which a post-processor is partitioned.
  • PIVOT-3647 Revamped Spring configuration classes to either define beans or import other classes.
  • PIVOT-2879 Do not notify Content Server listener when a non-readable child entry is updated.
  • APS-9893 Keep an aggregates cache for the latest version of each branch. The branches on which aggregates will be cached can be configured.
  • PIVOT-3371 FileSystemCSVTopicFactory now implements AutoCloseable. Usage in the sandbox has been modified (Spring Bean that auto-closes instead of the callback in the csv source close method)
  • PIVOT-3625 Update dependencies to their latest versions, notably Spring (→ 5.0.6) and Spring-security (→ 5.0.5).

Fixed

  • PIVOT-3626 Correctly publish retrieval additional measure across threads.
