1, 2, 3, 4, Add Another Data Store

1,223 views

Published on

In order to meet all our data needs including high volume ingestion, Map Reduce capabilities, real-time analytics, historical analytics, and other analysis technologies, we needed to incorporate the use of Redis, Mongo, a MySQL column store and Cassandra. Wrap the whole thing up in a Node.js API for speed and consistent access patterns and you have a whole data storage spread.
