Core

  • [fea] Added direct support for nested arrays storing/indexing in JSON, CJSON and MsgPack (i.e. JSONs like this { "id": 7, "arr": [ 1, "string", [ 1, 2, 3], { "field": 10 }] } now may be stored into database)
  • [fea] Allowed to sort null-values in hash-indexes (including null's inside arrays). Nulls-order is now consistent for different indexes/fields: null is considering less than any other value. This changes behavior for some queries with sparse tree indexes: previously nulls-order was inconsistent and had depent on the selection plan and index/field type
  • [fea] Added TagsMatcher's info into #memstats
  • [fea] Added fields check according to current StrictMode for joined fields inside ON-clause
  • [fea] Added Distinct-support for composite-indexes
  • [fix] Fixed assertion in ordered queries with Distinct over fulltext-indexes
  • [fix] Fixed background index optimization in cases, when target index contains null-values
  • [fix] Fixed CJSON-corruption after UPDATE-queries with non-existing array indexes

Fulltext

  • [fea] Improved merging logic, when MergeLimit is exceeded. Search engine will try to find documents with maximum corresponding terms. This may be slower, but provides better quality. You may set environment variable REINDEXER_NO_2PHASE_FT_MERGE=1 to disable 2-phase merging and fallback to the old merge logic
  • [fea] Supported select functions for array values in composite indexes
  • [fix] Allowed to index null-fields in fulltext composite indexes

Vector indexes

  • [fea] Added performance metrics for auto-embedding logic. Check indexes performance stats in #perfstats namespace for details (make sure, that perfstats are enabled in #config)
  • [fix] Fixed segmentation fault in KNN-queries with radius, when target index is empty
  • [fix] Disabled vector indexes update/create operations, when namespace does not have PK-index (it could led to disk storage corruption)

Go connector

  • [fea] Added support for nested arrays into CJSON-coding/decoding
  • [fix] Fixed Transactions with Update/Delete-queries. Now such transactions will return actual count of items, affected by the queries

Reindexer server

Reindexer tool

  • [fix] Fixed screening in \meta-calls

Face

  • [fea] Added total for Memory Statistics of namespace
  • [fix] Fixed issue appeared on Performance Statistics refresh
  • [fix] Fixed Embedder's URL validation to allow local domains
