--------------------------------------------------------------------
Do we need an option to relax these checks for STRICT mode? and allow arbitrary
fields in the Tuple, but ignore non-relevant while building a Row?
Maybe this could be a default option? If so, we only need this validation for
LIVE-schema to detect schema upgrades.

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

> 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 (TupleBuilder validated input against outdated schema version), then fallback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.
