Subject Re: Hadoop or RDBMS

Customer works already with Hadoop and doesn¹t want a RDMS on the side.
So maybe ElasticSearch for Hadoop or similar solution might be good for this
to guarantee performance for real time queries.

Given the relatively modest dataset size, this sounds like a straight
forward use case for a traditional RDBMS.

Is there some other criteria that's leading you to evaluate things built on
Hadoop? Are you expecting several orders of magnitude of growth in the
record count?
