Jetpants: a toolkit for huge MySQL topologies

From the webpage:

Tumblr is one of the largest users of MySQL on the web. At present, our data set consists of over 60 billion relational rows, adding up to 21 terabytes of unique relational data. Managing over 200 dedicated database servers can be a bit of a handful, so naturally we engineered some creative solutions to help automate our common processes.

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.

Dynamically resizable range-based sharding allows you to scale MySQL horizontally in a robust manner, without any need for a central lookup service or massive pre-allocation of tiny shards. Jetpants supports this range-based model by providing a fast way to split shards that are approaching capacity or I/O limitations. On our hardware, we can split a 750GB, billion-row pool in half in under six hours.

Jetpants can be obtained via GitHub or RubyGems.

Interested in this type of work? We’re hiring!

I am reminded of the line from The Blues Brothers film when Ray of Ray’s Music Exchange (played by Ray Charles) tells Jake and Elwood, “E-excuse me, uh, I don’t think there’s anything wrong with the action on this piano.”

Doesn’t look like there is anything wrong with the “action” on MySQL. 😉

Certainly worth taking a look.

I first saw this Alex Popescu’s myNoSQL.
