Key tuples are tuples with key columns only. Key columns always come first in the schema. So if there are 2 key columns, first two values of the tuple is the key.
Null vs NoValue
Ignite Table API handles "column set to null" (1) and "column not set" (2) differently.
- Non-nullable column does not allow (1), but allows (2) as long as there is a default value.
- Nullable column will be set to null in (1) and to default value in (2).
NoValue custom protocol type reflects this distinction.
