Core

  • [fea] Added background namespaces deleteion. Previously in some cases atomic transactions could cause the namespace's deletion in the querie's execution thread, which lead to the latency spike
  • [fea] Added locks and flush timings for UPDATE and DELETE queries into slow log
  • [fea] Added support for the COUNT/COUNT_CACHED aggregations for the MERGE-queries
  • [fea] Added basic support for the SUM/MAX/MIN aggregations for the MERGE-queries without LIMIT/OFFSET
  • [fea] Added more information about JOINs condtitions injection into explain (check on_conditions_injections field in the explain results)
  • [fea] Added field_type into the explain. This fields shows, which kind of field/comparator was used in the query: indexed or non-indexed
  • [fea] Added support for store (-) UUID indexes
  • [fea] Optimized string<->UUID convertions in the C++ library
  • [fix] Fixed total_us time calculation in the explain (previously preselect time was in the explain results, but was not counted in the total_us field)
  • [fix] Fixed JOINs conditions injection for the queries with multiple JOINs. Previously this optimization could skip some of the JOIN queries
  • [fix] Fixed multiple UPDATE arrays concatenation issues: empty arrays, string array, array with scalar, etc.
  • [fix] Composite indexes over the other composite indexes were explicitly disabled
  • [fix] Fixed check for nested JOINs and MERGEs (nested JOIN/MERGE is not allowed)
  • [fix] Multiple JSON-paths were explicitly disabled for the scalar indexes (multiple JSON-paths are allowed for composite and array indexes only)
  • [fix] Fixed crash on the CJSON deserialization for array indexes with multiple JSON-paths

Replication

  • [fix] Fixed handling of the updates buffer overflow (previously this logic may lead to multiple extra resyncs)

Fulltext

  • [fea] Added experimental support for Armenian, Hebrew, Arabic and Devanagari alphabets (prefixes/postfixes/suffixes search, typos, stop-words and synonyms are supported)

Reindexer server

  • [fix] Fixed SSE4.2 support check on startup (server has to print error message if SSE support is required for the current build)
  • [fix] Fixed DELETE-queries compatibility between reindexer_server v3 and reindexer_tool v4 in cproto mode
  • [fix] Fixed RPC-timeout handling (extra check for unread data wasd added). Previously connect could be dropped in case of the some very long queries

Go connector

  • [fea] Optimized string<->UUID convertions in the Go bindings
  • [fea] Default balancing algorithm for cproto was changed from RoundRobin to PowerOfTwoChoices. RoundRobin may still be enabled via WithConnPoolLoadBalancing option of the binding
  • [fix] Fixed transactions Commit/Rollback stucking in case of the incomatible items' sctructs in client and DB
  • [fix] Fixed builtinserver logger initialization in cases when single app run multiple instances of the builtinserver
  • [fix] Fixed RPC-connections background pinging (Ping requests became asynchronous)

Build

  • [fix] Fixed build with GCC 13.2

Face

  • [fea] Changed the numeric values position in the Grid
  • [fea] Added the ability to use spaces for JSON paths
  • [fix] Fixed the Statistics chart for undefined replication.wal_size
  • [fix] Fixed the column set for the namespace items during the namespace switching
  • [fix] Fixed the JSON paths view for values included spaces
  • [fix] Changed the value format for width on the integer for sqlquery
  • [fix] Fixed the bug related to the query history on the Namespace Items list
  • [fix] Fixed the column titles in the table settings menu on the Performance page
  • [fix] Added the validation of the negative values for the index settings
