I would also take a look at Hbase or Spark.

Thanks Harshit,  ElasticSearch for Hadoop seems a very good idea!

I am not sure, but ElasticSearch can be a good candidate for this.

Hi there,
We have build a (online) selection tool where marketeers can select their target groups for
marketing purposes eg direct mail or telemarketing.Now we were asked to build a similar selection
tool based on a Hadoop database. This database contains about 35 million records (companies)
with different fields to select on (Number of emplyees, Activity code, Geographical codes,
Legal form code, Turnover figures, Year of establishment and so on) 
Performance is very important for this online app. If one makes a selection with different
criteria, the number of selected records should be on your screen in (milli) seconds. 
We are not sure if Hadoop will be a good choice, for fast results we need a good indexed relational
database in our opinion…
Can anybody advise me?
Best regards,
James Peterzon
