First-Ever Redis Modules Hackathon

"The first place is awarded to Brandur Leach for his redis-cell module, which impressively delivers on several fronts. Primarily, redis-cell is a rate limiter that can readily be used to conserve the system's resources and protect it against unexpected loads."

Reading

The new UNLINK command

"Time complexity: O(1) for each key removed regardless of its size. Then the command does O(N) work in a different thread in order to reclaim memory, where N is the number of allocations the deleted objects where composed of."

The first release candidate of Redis 4.0 is out -

Modules / Replication version 2 / Cache eviction improvements / Non blocking DEL and FLUSHALL/FLUSHDB / Mixed RDB-AOF persistence format / The new MEMORY command / Redis Cluster is now NAT / Docker compatible.

Code and libraries

redismodule - Write Redis modules in Rust (WIP)

plug_rate_limit_redis - An Elixir plug rate limiting with redis

"In Elixir, since ETS is provided by Erlang runtime, it can process rate limit count within memory, but in real world there is no guarantee that it will not restart every time it is deployed and sometimes you want to share values with multiple servers I guess.
So I decided to allow Rate Limit with Redis, even if I restarted the Erlang runtime every deployment, I also made it possible to handle from multiple servers."

redis-lru: Redis-backed LRU cache for Node.js

A least recently used (LRU) cache backed by Redis, allowing data to be shared by multiple Node.JS processes. API inspired by node-lru-cache.
