Valentin Kulichenko commented on IGNITE-3084:
---------------------------------------------

[~NIzhikov], I don't agree on {{OPTION_GRID}}. In catalog implementation you 
already have Ignite instance, so I don't see why would you need to get it by 
name again. There should be another solution.

And in general, implementation detail should not drive public API. 
{{OPTION_GRID}} is very confusing and I still think it should be removed, at 
least in this iteration.

> Apache Spark already benefits from integration with Apache Ignite. The latter 
> provides shared RDDs, an implementation of Spark RDD, that help Spark to 
> share a state between Spark workers and execute SQL queries much faster. The 
> next logical step is to enable support for modern Spark Data Frames API in a 
> similar way.
> As a contributor, you will be fully in charge of the integration of Spark 
> Data Frame API and Apache Ignite.
