What's new

3.0.30160-Hotfix - 2016/11/08

TBA

3.0.30157-Hotfix - 2016/10/11

Server

  • [Configuration] Added Raven/SqlReplication/CommandTimeoutInSec setting,
  • [SQL Replication] Added CommandTimeout property to SqlReplicationConfig that allows to override command timeout per destination,
  • [SQL Replication] Fixed issue with setting LastReplicatedEtag when SQL batch times-out,
  • [Indexing] Removed support for using 'minimum ETag replacement strategy' when doing Side-By-Side on Map-Reduce indexes,
  • [Querying] Lucene will now escape text phrases AND and OR properly when they are not the operators

Client

  • [Side-By-Side] Client will throw when 'minimum ETag replacement strategy' is used on Map-Reduce indexes

FileSystem

  • [Client] Fixed possible NullReferenceException that can occur when file that does not exist is being loaded

Studio

  • Better memory utilization when viewing Running Tasks view

3.0.30156-Hotfix - 2016/09/26

Server

  • [Embedded] Prevented from conflicting RavenDB.Database and Metrics.Net assemblies loaded in the same project
  • [RavenFS] Fixed problem with declining reading performance in file systems with large number of files

Client

  • Fixed session.Advanced.LoadStartingWith with a transformer having LoadDocument which returned inconsistent results

Studio

  • Fixed an option to overwrite a name of an exported database file

3.0.30155 - 2016/09/16

This is an aggregated build for various fixes since the last stable

Server

  • [Performance] improved performance when loading huge amounts of databases in parallel,
  • [Configuration] added Raven/AllowNonAdminUsersToSetupPeriodicExport,
  • [Replication] fixes index and transformer replication that could cause index and transformer to revert to the previous version in some cases,
  • [Querying] fixed issue when using In operator with DateTime type,
  • [Subscriptions] better handling for synchronization when there are huge gaps during processing,
  • [Memory] better memory handling when performing memory intensive operations like bulk insert, storage and smuggler export to reduce the memory footprint

Client API

  • [Querying] fixed parsing issues that could occur in some cases when WhereIn is used,
  • fixed issue with Load returning null when duplicated ids are passed and transformer is used,
  • fixed loading data with includes when sharding is being used,
  • fixed a very rare case where concurrent modifications to the ReplicationDestinations could occur

Storage Exporter

  • added support for exporting attachments,
  • enhanced the export documents process,
  • better handling for OperationCanceledException

3.0.30153 - 2016/08/13

This is an aggregated build for various fixes since the last stable

Server

  • [Voron] stability improvements
  • [Indexing] side-by-side indexes will no longer unlock the index after swap,
  • [Indexing] side-by-side will detect better if the original index is identical and no swap is needed,
  • [Indexing] fixed a rare case in which under certain conditions we could run indexing on a same index concurrently,
  • [Indexing] we will not longer run reduction process for empty set of keys,
  • [Indexing] memory allocation improvements,
  • [Indexing] performance and stability improvements,
  • [Indexing] Optimize map/reduce operation for new indexes (avoid expensive DeleteMappedResults...),
  • [Prefetching] take into account availble memory when prefetching
  • [Replication] fixed possibility of infinite loop to occur in master-master replication under very rare conditions,
  • Better handling when the OS doesn't support file prefetching
  • Better errors if trying to open a corrupted document,
  • Fixed how we are computing the document size on Esent when prefetching,

Client API

  • [Bulk Insert] fixed possible hangs that could occur in a very long running bulk insert operation,
  • [Changes API] improved reconnection process
  • `[Querying] ContainsAny on empty arrays will no longer throw exception
  • fixed issue when you could load

FileSystem

  • fixed issue with synchronization process hangs when file for synchronization was in conflicted state,
  • improved synchronization performance by skipping file deletions if a relevant file does not exist on a destination server

Studio

  • added RavenJObject deserialization metrics

Storage Exporter

  • added support for exporting databases with compression and/or encryption,
  • added support for exporting transformers and indexes

Traffic

  • added support for system database
