Hello Aldo,
Yes, some low-level tricks could be possible. But it depends on two
things.
1) What are sizes of graphs in question?
2) With BNodes, what's the needed criterion to decide wither two BNodes
are equivalent?
Best Regards,

Hi,
What would be a PERFORMANT way of testing graph equality for two
graphs in the Quad store?
* A: without BNodes
* B: with BNodes
I am now using SPARUL and temp graphs to generate a diff, but I
imagine there is a better way ( using low level APIs perhaps? ).
Regards,
A

in the following paragraph:
When expressions occur in result sets, many variables are introduced
only to pass a value from triple pattern to the result expression.
This is inconvenient because many triple patterns are trivial. Big
