Oracle Coherence That's completely wrong. TimesTen and Coherence are 2 separate products sold by Oracle. Coherence is a data grid that takes a key/value approach. It is massively scalable across LAN and WAN. In terms of comparing Cassandra and Coherence, I wouldn't. Coherence is a data grid and most often used as a fault tolerant distributed cache, though it does a lot more than that. Oracle bought Tangosol a few years back.
