Hello, guys.
I have done prototype of implementation of optimization query from Spark to
Ignite [1].
Please, take a look at PR [2].
But still there are some issues I want to clarify with community:
* Can I know scale and precision of DECIMAL column?
Example - [3]
* Ignite have some limitation for a *distributed* join. For example, we can
execute join only for indexed columns. Example - [4].
* Do we have documentation for all limitations of distributed join
implementation?
* How can I know whether concrete syntactically correct SQL query with
join can be executed by Ignite or not?
