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.
This blog is called myNoSQL and it is written by me, Alex Popescu, a software architect with a passion for open source and communities.
It records my readings, learnings, and opinions on NoSQL databases, polyglot persistence, and distributed systems -- subjects that I'm passionate about.
The opinions expressed here are my own, and no other party necessarily agrees with them.
If you feel I'm biased, I probably am.
