Subject Re: DataFrame support for Ignite queries

Great drill down analysis. Thanks, Val!

I think, that this kind of integration between Spark and Ignite will be truly useful if we
support a logical to physical plan conversion executing a query directly over the data cached
in Ignite. Not sure that it worth our efforts to support Ignite just as one more Spark data
source if, eventually, Spark still will prepare RDDs internally by copying data at query execution

Do you have an understanding on the efforts to support the logical to physical plan conversion?
Do we need to ask Sergi or someone else from the community to investigate this deeper?
