5.8.8

2020-02-18

Changed

• APS-12399 The AggregatesEvent of the ws-client module now contains a branch field containing the name of the branch on which the event occured.
• APS-12443 Changed CSVParserConfiguration full constructor. It now takes one more boolean argument, acceptIncompleteLines, which states whether the parser should take into account a line whose number of columns is smaller than the expected, or not.

Deprecated

• APS-12443 CSVParserConfiguration full constructor now takes one more boolean argument, acceptIncompleteLines. The previous constructor will be removed in version 5.9.0.

Fixed

• APS-12391 Fix a NullPointerException that occured when removing a data node and readding it to the cluster within removalDelay seconds.
• APS-12399 Fix the XML serialization of the FullRefreshEvent.
• APS-12443 acceptIncompleteLines set to false properly throws when the last line of a csv file is incomplete.
• APS-12458 Fix a StreamCorruptedError that could happen in NettyInputStream after receiving an exception message, and wrongly resetting the stream's reading index.
• APS-12466 Fix a RuntimeException about non shared-dictionaries that could happen when querying a Join-defined measure defined in Copper 2 in a distributed scenario with multiple join operations.
• APS-12477 Fix the declared output type of the AverageFunction aggregation function to match the type of the returned aggregates.
• APS-12498 Fix an issue in QfsFiles that caused the getResourceAsStream method to delete first character of the given path when running with OpenJdk11.0.6 (or later) and trying to access resources inside a jar.

5.8.7

2020-01-17

Added

• APS-12141 Support for plus & minus between vector and scalar in Copper 2
• APS-12329 Added method withDescription to set a description of your measure in Copper 2

Changed

• APS-12370 Improve the error message when a measure is declared with an invalid formatter.
• APS-12400 Improve MDX boolean functions evaluation. Instead of an eager evaluation on both arguments we double-check if the first argument absorbe the second one, in which case the evaluation of the latter is ignored.

Fixed

• APS-11728 Fix an 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-12305 Fixed an issue with branch deletion in a distributed cluster, causing a small memory leak for each deleted branch.
• APS-12374 Fix an issue with the publication of optimized measures in Copper 2.
• APS-12383 Change the Datastore-related ICondition's equals() method so that two instances are now considered equal if their sub-conditions are permutations of each other.
• 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-12393 Fix a measure publication issue in Copper 2 when calling filter() on an already filtered measure.
• PIVOT-4136 Fix MeasuresDetail attribute in the partial provider MBean.

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-12179 Updated nimbus-jose dependency version to 8.2 to avoid a potential vulnerability.
• PIVOT-4120 BREAKING: CopperMeasure.at now takes fully defined CopperLevel instead of the level's name as arguments.
• PIVOT-4120 BREAKING: If you use Copper.level(levelName) then Copper APIs receiving it will now throw if several levels match instead of picking the first one. You should use Copper.level(dimensionName, hierarchyName, levelName) instead. Same for Copper.hierarchy(hierarchyName).
• PIVOT-4137 Better Object to primitive conversion in Records.
• PIVOT-4137 Do not push idempotent locale changes in the content server.
• PIVOT-4137 Made the datastore configuration optional in ActivePivotServicesConfig.

  • IInternalAggregatesRetrievalResult#join(..) without ICubeFilter
  • IInternalAggregatesRetrievalResult#expandResult(List<? extends IHierarchy>, List<? extends ILevelInfo>)

Fixed

• APS-12082 In some cases the server could send a transient empty drillthrough result when the actual result was computed. This is no more the case.

• APS-12136 Fix publication of implicit hierarchies due to joins made in Copper
• APS-12215 Correctly set retrieval results filters when Analysis Hierarchies are involved. It previously resulted in missing results.
• APS-12217 Fix name generation when using cube as datacube
• APS-12227 Fixed JSON queries that wrongly locked all stores
• APS-12240 Fix the partitioning levels of the Copper shift operations when data is partitioned on a level of the shifted hierarchy.
• APS-12299 Fix a NoSuchElementException that could happen while using a Copper 2 shift operation defined with a lambda along a cube filter.

5.8.0

2019-04-15

Added

• PIVOT-3622 Integrate the Cloud Source to the core product.

Changed

• PIVOT-3839 Datastore and Copper tests have been moved to their own modules (com.activeviam.tech:datastore-test and com.activeviam.activepivot:activepivot-copper-test)

• 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.

  APS-10692 The appendQueueSize attribute is no longer part of the AJDBCSource, but rather the JDBCTopic.

  Read the migration notes for more details.

• APS-10998 The ICubeFilterBuilder.includeMembers method accepting wildcards for members path name (eg. List<?>) has been moved to includeMembersWithConditions. 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-9927 The ActivePivot Sandbox now has a 4-Level Hierarchy (the 'LegalEntity' and 'BusinessUnit' levels have been added on top of the already existing Booking hierarchy)

• APS-10705 The sandbox project properly configures its firewall to support special chars in file names for the Content Server.

• PIVOT-3866 IEpochHistory.markHead() and IEpochHistory.markHead(String branch) now return the IEpoch that was marked instead of void.

• APS-11427 The metadata fetching methods of the JDBCSource have been modified to not rely on a non-standard behavior of JDBC Driver implementation of ResultSetMetaData.getColumnName(), but instead use the standardized ResultSetMetaData.getColumnLabel()

• APS-11423 Improve the logs for notifications generated by real-time queries.

• PIVOT-3906 Rewrite the tasks performing Range-Sharing to avoid potential assertion failures.

• PIVOT-3943 Perform the hierarchy contributions (during a Pivot commit) in parallel; this can speed up commit times in configurations with many hierarchies.

• {@jira: APS-11920, PIVOT-3005} ActivePivot queries now return "NaN" for Double.NaN values instead of "\uFFFD" (�).

Deprecated

• PIVOT-3670 An ISelectionListener does not record changes anymore, so it has no reason to be cleared anymore. The functions cleared() and isClearable() will be removed in 5.9.

Removed

• PIVOT-3834 The changes introduced in Post Processors V2 in 5.7.3 are now merged into the normal implementation of the post processors. Read the migration notes for more details. The following post processors V2 have been removed :

• PIVOT-3760 Correct replanning of aggregation procedure dependencies
• APS-10971 Ensures that retrievals computing the logic of Aggregation Procedures returns a true retrieval result. This fixes IllegalStateException complaining about "an unplanned retrieval (no primitive result)".
• APS-10846 Remove the incorrect check in memory monitoring report, causing UnsupportedOperationException.
• PIVOT-3663 Releasing a branch in a data cube does not throw an exception during the planning of a query in the query cube

Fixed

• APS-10706 fix Aggregates Cache Statistics; the MBean also displays pivot version and branch name for the statistics.
• PIVOT-3676 The DistinctCountFunction now has an aggregated datatype of LONG instead of the same type as its inputType.
• PIVOT-3659 CoPPer now supports using aliases for fields in the base store

• 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.

• 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

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.
