-----------------------------------------
> BTW, as a general note, I see that there are still many methods throwing
> UnsupportedOperationException, at least in the IgniteExternalCatalog
> Do we know what are the features that we still do not support? Is it possible
> to create a list of them and then the tickets to address later?
Yes, I will create tickets for feature to implement in
{{IgniteExternalCatalog}} in a few days.
