Subject Re: more concurrency issues with requests management?
Date Fri, 22 Feb 2013 13:16:15 GMT
Sorry for missing that detail, my bad.

Personally I do not see why we cannot have a (2^31) bytes array, which
would not solve my problem anyway.
I guess at this point I'll have to go for multiple ExtendedDataOutput per
vertex, and the EdgeIterator just "concatenates" them?

I do not want to go into the details, but I want a number of messages that
is the same as the edges in the graph.
