MemoryTableRelation

open class MemoryTableRelation : Relation, StoredRelation, RelationDefaultChangeObserverImplementation

An in-memory mutable Relation. Conceptually similar to ConcreteRelation, except that this is a reference type rather than a value type, and so behaves more like we might expect a table to. It’s also observable, in case you need that sort of thing.
