JAQL is a query language and engine which has XQuery-like syntax, SQL-like operators, JSON as a native data format, and runs using the Hadoop ma/preduce framework. (Although not mentioned explicitly, it's probably great for social networking as well...)
You might think that JAQL and JEQL were separated at birth, but they actually have no genetic material in common. But it's interesting to see the J*QL acronym space being rapidly populated. The best two vowels are now gone - who's going to be next to pile in?
