I am still new with cassandra and from what I know so far cassandra is based on Google BigTables model. And one thing that we can do with BigTable is query data using GQL. I tried looking for information about query language that is built on top of cassandra and ends with no luck. The only way we can query over data is either using Range query or Hadoop Map-Reduce. CMIIW. Now with range query, it would be less expressive than query language while with Hadoop Map-Reduce I have heard that it is not suitable for realtime data query. So is it possible to implement query language on top of Cassandra? Or is MapReduce and range query the only option we have?
Thanks for the insights.
