Cassandra on RocksDB

Tuesday 5:25PM-5:50PM

@ Room M2

Open Source Databases

25 minutes conference



This year the Cassandra team in Instagram has been working on a very interesting project to make Apache Cassandra's storage engine pluggable, and implemented a new RocksDB-based storage engine into Cassandra. The new storage engine can improve the performance of Apache Cassandra significantly, make Cassandra 3-4 times faster in general, and even 100 times faster in some use cases.

In this talk, we will describe the motivation and different approaches we have considered, the high-level design of the solution we choose, also the performance metrics in benchmark and production environments.
