Metamarkets open sources distributed database Druid by Elliot Bentley.

From the post:

It’s no secret that the latest challenge for the ‘big data’ movement is moving from batch processing to real-time analysis. Metamarkets, who provide “Data Science-as-a-Service” business analytics, last year revealed details of in-house distributed database Druid – and have this week released it as an open source project.

Druid was designed to solve the problem of a database which allows multi-dimensional queries on data as and when it arrives. The company originally experimented with both relational and NoSQL databases, but concluded they were not fast enough for their needs and so rolled out their own.

The company claims that Druid’s scan speed is “33M rows per second per core”, able to ingest “up to 10K incoming records per second per node”. An earlier blog post outlines how the company managed to achieve scan speeds of 26B records per second using horizontal scaling. It does this via a distributed architecture, column orientation and bitmap indices.

It was exciting to read about Druid last year.

Now to see how exciting Druid is in fact!
