>             Project: Ignite
>          Issue Type: Improvement
>            Reporter: Andrey Mashenkov
>            Priority: Major

> h3. Motivation.
> At a point of Table public method is called by a user, we need to validate user input (for LIVE-schema purposes at least).
> h3. Description.
> We can add this logic to check if value fields match the current schema version (no new fields).
>  * For LIVE-Schema. If Tuple has one or more additional columns, then we should try to register a new schema first, then proceed with the user operation.
>  * For STRICT-Schema.  If Tuple has one or more additional columns, then we should fail the user operation.
>  * For KeyValueView, we should validate key Tuple as well, and fail if there are unknown columns. Because a key column span is immutable. The only exception may be if a user creates a schemaless table, then a schema of the 1-st version should be registered instantly.
> Assumed, any column type mismatch or missed Non-Nullable columns will be caught and processed by RowAssembler.
> h4. Possible optimization.
> It is possible to add the validation into a TupleBuilder and then just check the Tuple instance class (should be a builder). 
>  For any Tuple of unknown type or if a schema was changed concurrently (TupleBuilder validated input against outdated schema version), then fallback to default logic and re-validate input against the latest schema.
