v5.10.0

Core

• [fea] Added filtering by field length
• [fea] Optimized selection plan for tree sparse-indexes with is null/is not null conditions
• [fea] Support multifield sort by tree sparse-indexes
• [fea] Improved index detection logic for target fields in update-queries in cases, when jsonpath does not equal to index name
• [fix] Fixed arrays concatenation for sparse-indexes
• [fix] Fixed assertion throw for non-existing fields in forced sort
• [fix] Fixed multiple issues with collate numeric index option: null-values handling and space characters handling
• [fix] Fixed original strings content preservation for collate ascii and collate utf-8 (previously those strings could be normalized)
• [fix] Disabled invalid config with multiple jsonpaths for geo indexes
• [fix] Fixed update drop for heterogenious arrays with sparse-indexes
• [fix] Fixed array fields rollback for unsuccessful update-queries in some corner cases

Fulltext

• [fea] Added terms concatenation. Enabled by default. Check EnableTermsConcat flag and ConcatProc value
• [fix] Fixed crash on null-values with enable_preselect_before_ft: true index option

Vector indexes

• [fea] Added embed_input_traffic and output_traffic prometheus metrics for auto-embedding
• [fea] Added skip_embedding() precept for vector fields. Check embedding configuration for details
• [fix] Fixed auto-embedding statistics in #perfstats after vector index update

Replication

• [fea] Added queued_namespace_syncs field into #replicationstats. It shows current WAL/force-sync queue size for each node
• [fea] Improved namespaces sync ordering. Now replicator tries to achieve better vectors data sharing
• [fea] Extended admissible_replication_tokens functionality: now those tokens may be used on leader to protect it from role switch by other node (useful in scenarios, when follower has to become new leader)

Go connector

• [fix] Fixed panic in case of inner join with closed namespace

C++ connector

• [fea] Added support for array-fields setting via Item::operator[]

Reindexer tool

• [fea] Improved interaction with between DB dump restoration and auto-embedding: auto-embedding will be skipped for existing data

Face

• [fea] Added enable_terms_concat and concat_proc setting into text-index page
• [fix] Fixed item template on New item page for interfering nested keys
