I was following those posts; thought it was curious that no one seemed to be interested in them. Now that i see where your research wound up I'll follow your posts back to read and catch up on them.
You might have already found this and i haven't caught up with you yet, or maybe this is nothing. Several of these posts referred to "Cassandra" being taken down. A quick search of Cassandra brought this: https:// en.m.wikipedia.org/wiki/Apache_Cassandra
Does the reference to Apache make it relevant?
