-----------------------------------------
Hello, [~tledkov-gridgain].
Thanks for the review.
> Why we need this implementation?
To made Ignite better, obviously.
I, personally, need this feature to make better integration with Spark Data
Frame.
I should provide column type for Data Frame schema and I want to use scale and
precision from table metadata.
Please, see [1] from current master.
> I'm afraid that the user may be confused the contradiction between right

AFAIK it's a current Ignite behaviour.
So, it's already confusing a user who wants to restrict DECIMAL columns.
I thought that *wrong query results* is a bug so we have a plan to fix it.
Am I wrong?
