Which flavor of Nosql database should I learn ?

[ni4ni]

Hello

As an experienced Oracle DBA, I started exploring Big Data solutions, thinking its a good direction to move in my career.

However, when I try to decide Which of the Big Data solutions I want to learn I find it really hard to decide. There are so many of them, and the technology is not mature yet so you can not tell Which of them will survive in the long run.

So I tried looking for open positions, thinking that this way I can feel Which are the "strong" solutions in the industry. This confused me even more. Some of the companies do not even mention what technology they want, they just say: "A Big Data DBA needed", even without specifiying what flavor of Big Data DB they have!

As a technical person, a DBA, what solution should I learn? Which of them do you think will last and become most widely used?

Thanks

Guy

I'd get a broad overview first, since based on the type of processing the "best" solution varies. Start with something like Seven Databases in Seven Weeks:

Given your Oracle background, you might want to start with their Oracle NOSQL product, which is essentially an implementation of Berkeley DB for Java.

From a sheer noise (maybe popularity perspective?), the main
contenders seem to be:

MongoDB
Neo4J
Cassandra

Hello Guy,

I'm a long time Oracle DBA that is picking up "big data" tech skills as well…

I strongly recommend  Hadoop/Hbase and MongoDB

Thanks for all the answers.

Oracle's NOSQLDB is tempting because its Oracle and companies (those who are not startups or cutting edge technology) tend to go for "big brand" solutions and not community/open source driven solutions). However, at this point it feels not mature enough and inferior to other leading technologies in this field.

I will not be surprised if Oracle will abandon current NOSQLDB in the future in favor of a better solution (home developed or by buying one of the DB's out there).
