Nullability mark for optional type can not be processed when creating tables with YQL

[kaifeur]

CREATE TABLE `a` (
    `b` Int64?,
    PRIMARY KEY (`b`)
);

This script can't be executed because of YQL type incompatibility error. It's quite strange considering that YDB supports only nullable types.

Of course, if there is no plans for the future support of non-nullable types, then we can create nullable columns without nullability mark.

All columns in CREATE TABLE are already nullable by default, no explicit optional mark required (it will actually add second level of optionality).

Non-nullable types will be supported later with NOT NULL column setting:

CREATE TABLE Test (
    Key Int64 NOT NULL,
    PRIMARY KEY (Key)
);

Non-nullable types will be supported later with NOT NULL column setting:

Excuse me for offtopic, but how seen it will be supported in serverless YDB?

We'll report in #4 once it is available.
