But now we're considering the alternative of reading/writing the whole graph at once and process queries in memory. If "the whole graph" is too big to fit in memory without problems, then we should find a way to partition it._______________________________________________On Sat, Dec 17, 2016 at 2:54 AM, John Sanda <jsanda@redhat.com> wrote:This thread post https://goo.gl/8cpSwMfrom cassandra-users list has a good write up on an approach for implementing transactions across multiple tables in order to provide stronger consistency. I found it particularly interesting in light of the discussions of inventory and consistency. - John
