v3.27.0

Core

• [fea] Decreased heap allocations count in general selection pipeline
• [fea] Optimized allocations in fulltext query preparation phase
• [fea] Added heuristic for copying transactions, which allows to avoid extra namespace copying if there are no select queries expected. May be disabled via REINDEXER_NOTXHEURISTIC env variable
• [fea] Added automatic default values setting on new index creation (except UUID and rtree indexes)
• [fea] Improved comparators performance for IN()-conditions
• [fix] Fixed potential deadlock on data reading at server startup
• [fix] Fixed double fulltext index building after copying transactions
• [fix] Fixed incorrect composite indexes detection in some of UPDATE-queries (it could lead to random crashes during updates)
• [ref] Deprecated fulltext index option warmup_on_ns_copy. In current implementation reindexer will always build fulltext index after copying transaction
• [ref] Removed some of the default RU stop-words

Replication

• [fix] Fixed updated_unix_nano in #memstats table
• [fix] Disabled statement-based update replication - in some cases it could lead to crashes and data loss due to logic conflicts in WAL

Reindexer server

• [fea] Added SO_LINGER-option in cases when client drops connection first. This allows to prevent TIME_WAIT socket state on the client's side

Deploy

• [fea] Added build for Ubuntu 24.04
• [ref] CentOS 7 reindexer repo is no longer supported due to CentOS 7 EOL

Face

• [fea] Added RU language in UI
• [fix] Fixed input width in settings section
