Can the default graph be defined as the union of all named graphs?

[Daniel Hernández]

hi all,

I have a dataset that have millions of named graph and I want to
query a property path against the union of all. It is not practical
to list all named graphs with FROM clauses, because they are millions.
Thus, I wan't to know if it is possible to set fuseki to assume
that the default graph is the union of all named graphs.

Thanks,
Daniel
