Tumblr Jetpants: A Toolkit for Huge MySQL Topologies

Jetpants:

Today, we’re happy to announce the open source release of Jetpants, Tumblr’s in-house toolchain for managing huge MySQL database topologies. Jetpants offers a command suite for easily cloning replicas, rebalancing shards, and performing master promotions. It’s also a full Ruby library for use in developing custom billion-row migration scripts, automating database manipulations, and copying huge files quickly to multiple remote destinations.

This toolkit helps Tumblr manage its 60bn rows totaling 21TB of data in a MySQL cluster.
