Description

Fuseki is not aware that some transactions are fully ACID not just locking.

It could rely on the transaction semantics and not need to buffer request data to verify it.

Consider a special wrapper to make non-TDB datasets have weak transaction semantics.

DatasetGraphs need a "capabilities" mechanism. c.f. c.h.h.j.sparql.util.Context and c.h.h.j.graph.Capabilities.
