Andy Seaborne commented on JENA-1236:
-
I've only thought about inference - each setup has to considered on a
case-by-case basis for this general mixed collection scenario.
There are some conditions that must hold like the wrapping graph is itself
stateless over restarts so if it adds a separate feature like specializes index
then "it's complicated" and needs separate thinking.
The transaction mechanism in DBOE/TDB2 can handle this better. It is general
and not tied to one storage but we need a solution now as well.
