-----------------------------------------

[~vkulichenko], we almost reached code freeze for AI 2.7. Will you be able to complete it
by 30 Sept 2018?

> {{IgniteDataFrameExample}} creates two tables - {{city}} and {{person}}, but only {{person}}
is actually used. Need to add join examples.
> Would also be great to demonstrate the fact that optimization is working and joins are
executed in Ignite, not Spark (using {{explain()}}, maybe?).
