## 简介
|
||
|
||
Other online schema-change tools I’m familiar with (e.g. pt-online-schema-change) use triggers to keep a new table in sync with changes while copying old rows over. Instead, gh-ost monitors changes by hooking on as a replication slave. Very clever! This article goes into several reasons why this is a much better approach.
