## 简介
|
||
|
||
Facebook rewrote their tool, OnlineSchemaChange in Python (from the original PHP). OSC is a tool for doing DDL in MySQL without downtime.
|
||
|
||
> The original open sourced OSC was more like an engine than a tool. Users needed to write PHP code wrapping to run the schema change, and, with PHP becoming less popular in the operations world, OSC.php wasn’t widely adopted by the community.
