Reading

84% of a single-threaded 1KB write in Redis is spent in the kernel

The performance of live site systems — everything from K/V stores to lock servers — is still measured principally in latency and throughput. Server I/O performance still matters here. It is impossible to do well on either of these metrics without a performant I/O subsystem. It is worth wondering: are standard commodity OSs even equipped to deliver these I/O improvements?

Code and libraries

rolling-rate-limiter - Rate limiter for node.js that supports a rolling window backed by redis

This is an implementation of a rate limiter in node.js that allows for rate limiting with a rolling window. This contrasts with many existing implementations, in which a user could make 5 requests at 0:59 and another 5 requests at 1:01.

Lua Library

Public domain Lua scripts for your use or reference.

node-cartodb-redis - interact with the cartodb redis database

lettuce - A scalable Java Redis client

Lettuce is a scalable thread-safe Redis client providing both synchronous and asynchronous connections. Multiple threads may share one connection provided they avoid blocking and transactional operations such as BLPOP, and MULTI/EXEC. Multiple connections are efficiently managed by the excellent netty NIO framework. Support for advanced redis features such as Sentinel, Cluster and redis data models is included.

redis-failover - Automatic redis monitoring and failover based on Raft and Go
