Spotify and The Last Pickle (TLP) have collaborated over the past year to build Medusa, a backup and restore system for Apache Cassandra which is now fully open sourced under the Apache License 2.0.

TLP is looking to hire someone in America to work with us on tough problems for some of the biggest and smallest companies in the world. We help our customers get the best out of Apache Cassandra, and we have a really simple approach: be smart, be nice, and try to make it fun. Our customers range from large corporates to well-known internet companies to small startups. They call on TLP to fix and improve the Cassandra clusters they use to deliver products and services to millions of users, and sometimes to hundreds of millions. We’ve been doing this since 2011 so if you have used the internet there is a good chance TLP has worked with at least one company you have visited.

Tombstones are notorious for causing issues in Apache Cassandra. They often become a problem when Cassandra is not able to purge them in a timely fashion. Delays in purging happen because there are a number of conditions that must be met before a tombstone can be dropped.

Next week we’ll be in Las Vegas for the North American ApacheCon Conference. From the TLP consulting team Anthony will be giving a talk on the open source tooling we’ve developed to provision and stress test clusters. Aaron and I will be at our booth giving demos all week. We’d love to chat with you about Cassandra internals, application development, performance tuning, our open source tools, Cassandra best practices, and hear your story. We’ll also be more than happy to give you a demo of something special we’ve been working on this year.
