Hi all,

I execute simple SQL query and got a unacceptable performance.

I do the following steps:

1. Apply a schema to an RDD and register table.


2. Run sql query which returns several entries:
        

Running time for this query 0.2s (table contains 100000 entries). I think
that Spark SQL has full in-memory scan and index might increase performance.
How can I add indexes?
