> Currently queries like this do not work in Ignite if we use enum field on the left side and enum constant name or ordinal on the right side:
> select * from A where my_enum = 'ENUM_CONST';
> select * from A where my_enum = 3;
> This is a huge usability issue.
> We can try to solve it by contributing `User defined Value types` in H2 and implementing the special value type for Enums to handle comparison with String (convert to enum by name) and with int (convert to enum by ordinal).
