Real World Tales of Repair (Alexander Dejanovski, The Last Pickle) | Cassandra Summit 2016

Slides: https://www.slideshare.net/DataStax/r... | The Anti-Entropy process used by nodetool repair is the way of ensuring consistency of data on disk. Over the many years of the Apache Cassandra project it has also been the biggest pain point for teams running Cassandra. With a solid repair process in place you can be confident that deleted data will not come back to life, and that data is fully distributed when nodes fail. In this talk Alexander Dejanovski, Consultant at The Last Pickle, will explain how Anti-Entropy works and why it should be run on your cluster. He will discuss the different options such as ""primary range"" repair, sub-range repairs, and incremental repair introduced in version 2.1. He will also introduce additional tools such as the Spotify Reaper and the range repair script, and future optimisations incremental repair could bring to the read path.
