Scaling Datastores at Slack with Vitess (via) Slack spent three years migrating 99% of their MySQL query load to run against Vitess, the open source MySQL sharding system originally built by YouTube. “Today, we serve 2.3 million QPS at peak. 2M of those queries are reads and 300K are writes. Our median query latency is 2 ms, and our p99 query latency is 11 ms.” # 1st December 2020, 9:30 pm

Spock Proxy. A MySQL Proxy fork (no Lua) that concentrates solely on sharding, by parsing incoming SQL statements and redirecting them across multiple databases. There are some limitations on the SQL that can be handled (no nested queries, joins across a maximum of two tables) but generally it looks pretty impressive. # 11th December 2008, 9:49 am
