NoSQL Databases - What's Changed?

Cray sees the convergence of HPC (high performance computing) and big data.

The graph database market is starting to consolidate. There are also interesting graph and associative database developments

You need a good optimiser to get decent SQL performance from Hadoop.

If you implement a different database on top of Hadoop is it still Hadoop? If you replace the file system in Hadoop (or MongoDB) is still Hadoop?

Adding SQL to a NoSQL database will only be of limited value unless you also have a database optimiser

In this paper we will not only discuss what big data is and why you might want to deploy big data analytics but also what sort of facilities you need when combining Hadoop with a traditional warehouse.

You can combine DataStax's distribution of Cassandra on the same cluster as Hadoop

What makes Hadapt different is that it combines both Hadoop-based and relational storage
