What do you recommend for organizations considering Hbase for their database management needs?

What is Hbase used for?

In HBase, we cannot implement any cross data operations and joining operations, of course, we can implement the joining operations using MapReduce, which would take a lot of time to designing and development. How we can improve this and reduce the timings??

Other features which we can use of HBase other than just storing data.

For one of the client, i received a request for setup DR for Hbase open-source project

How do I make maximum use of hbase? What is the best way to work with hbase integration? Can I use it for RDBMS purposes?

I am a fond user of SQL hence this question. Also HBase is one of the older players in the market so what are your plans to compete with Apache DRUID? Apache Superset is also a great tool for visualization. Do you have any plans to integrate HBase with Apache Superset?
