Concurrent Query Execution With Isolation Guarantees

via “concurrent query execution with thread-safe locking”

A query and indexing engine for Redis, providing secondary indexing, full-text search, vector similarity search and aggregations.

Unique: Uses reader-writer locks to allow concurrent read-only queries while serializing write operations, integrated with Redis' event loop for non-blocking execution; garbage collection runs asynchronously to avoid blocking queries during cleanup

vs others: More efficient than global locking because read-only queries don't block each other; simpler than optimistic locking because Redis' single-threaded event loop simplifies synchronization
