Zedis is a high-performance, Redis-compatible in-memory data store written in Zig. It implements the RESP protocol and supports core Redis data structures (strings, lists, TTL, pub/sub) along with advanced features: time-series with Gorilla compression, full-text search with BM25 and vector KNN (FLAT), probabilistic Bloom filters, and both AOF and RDB persistence. The architecture uses a multi-threaded server with a dedicated store thread for serialized command execution, custom budgeted allocators, and a lock-free client mailbox for message passing. While production-ready in capability, the project is explicitly designed for learning and experimentation and shows some documentation-to-code drift and a handful of unmaintained TODO items. It includes an extensive benchmark suite comparing against Valkey.
