SQL and MongoDB

It has been a long time since I had used MongoDB. In the meantime I am very interested in the possibility to use plain SQL when working with MongoDB.

At first my toolbelt has the https://robomongo.org/ tool. This tool allow to ease the work with Mongo console. How can use SQL? That's the main question. There is a project Apache Drill which allows you to connect to MongoDB, Hadoop, Hbase, files and query with SQL. Moreover, you can use the Apache Drill jdbc driver with any tools that support JDBC!
Pretty good!
