Redislistat

Redislistat is a Redis extension that provides an enhanced list data type designed for high-throughput applications requiring atomic multi-element operations and richer metadata. Implemented as a Redis module, it exposes commands and language bindings to create, modify, query, and manage lists. The core data type combines traditional list semantics with per-item metadata such as timestamps and optional versioning, enabling advanced querying and time-aware processing.

The architecture centers on a C-based Redis module that implements a dedicated list type and a service layer for batch operations. It runs within the Redis server process and cooperates with Redis features such as transactions, Lua scripting, and Redis Cluster. The module includes native support for range queries, bounded-size lists, and efficient truncation, as well as optional per-item expiration.

Operations include pushing and popping items, indexing, range retrieval, trimming, and metadata access. Commands are designed to be composable with Redis transactions and Lua scripts, and client libraries exist for major programming languages.

Redislistat emphasizes persistence and reliability through compatibility with Redis persistence mechanisms, including RDB snapshots and AOF, and it supports clustering by partitioning lists across nodes. It aims to deliver predictable latency and controlled memory usage for large lists.

Common use cases are real-time feeds, task queues, event histories, and dashboards that require ordered views with metadata. The project originated in 2023 as an open-source effort and has since seen multiple releases and community involvement.
