What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded

Twitter's fork of MySQL 5.5 with internal enhancements such as extra InnoDB status variables, NUMA-aware memory allocation, and replication improvements. It was published to share code but is explicitly not intended for use outside Twitter.

Use cases

run a MySQL server with better InnoDB observability
optimize MySQL buffer pool allocation on NUMA hardware
monitor InnoDB deadlocks and open tablespace files
use dynamic replication filters in MySQL
study Twitter's production MySQL modifications

When to choose

you are researching Twitter's database engineering practices
you need the specific NUMA or status-variable patches on MySQL 5.5
you want a historical reference for WebScaleSQL-era MySQL forks

When to avoid

you need a supported, up-to-date database server
you are not Twitter and want bug fixes or maintenance guarantees
you need modern MySQL features from 5.7 or 8.0
