Facebook 把自家的 MySQL 升級到 8.0

Facebook Engineering 發了一篇將 MySQL 升級到 8.0 的說明：「Migrating Facebook to MySQL 8.0」。

先前的版本主要是 5.6，加上 MyRocks：

Our last major version upgrade, to MySQL 5.6, took more than a year to roll out. When version 5.7 was released, we were still in the midst of developing our LSM-Tree storage engine, MyRocks, on version 5.6. Since upgrading to 5.7 while simultaneously building a new storage engine would have significantly slowed the progress on MyRocks, we opted to stay with 5.6 until MyRocks was complete. MySQL 8.0 was announced as we were finishing the rollout of MyRocks to our user database (UDB) service tier.

在 GitHub 上是有 facebook/mysql-8.0，但看起來從 2017 後就沒更新了，所以應該是沒有 open source 出來。

看看就好 XD

Percona 推出 MySQL 8.0 的對應版本了...

Percona 在過節前推出 Percona Server for MySQL 8.0 了：「Announcing General Availability of Percona Server for MySQL 8.0」。

在 Oracle 版的 MySQL 8.0 多了不少功能，像是往 NoSQL 靠的功能與 GIS 相關的功能，但讓我注意到的是 Percona 自己的事情... TokuDB 因為 MyRocks 而要被放生了：

Features Being Deprecated in Percona Server for MySQL 8.0
TokuDB Storage Engine: TokuDB will be supported throughout the Percona Server for MySQL 8.0 release series, but will not be available in the next major release. Percona encourages TokuDB users to explore the MyRocks Storage Engine which provides similar benefits for the majority of workloads and has better optimized support for modern hardware.
