Interface IJoinEntry

The original query operation from which the bindings stream was produced.

If the operation is not the original operation, but is only created to simulate the output stream. If this field is set, this usually means that the output should be directly used, while using the operation would lead to sub-optimal performance. This is for example set in bind-join-like actors.

If pushing the join into the given operation must be preferred over using the output stream directly. This will for example prefer bind-join-like actors.

A (lazy) resolved bindings stream, from which metadata may be obtained.
