> Looks like ALTER COLUMN commands could be used only on a subset of supported types (that could be used in CREATE TABLE syntax):
> [https://apacheignite-sql.readme.io/docs/data-types]
> But using query entities we can provide to use a field that has user types.
> This fields can be used in 
> ALTER TABLE CACHE_NAME DROP COLUMN COLUMN_NAME
> But it can't be used as next:
> ALTER TABLE CACHE_NAME  ADD COLUMN COLUMN_NAME 'type'
> Where type is a user's one.
> Possible we should think about supporting POJO and enums.
