Subject Re: Cassandra and Oracle Coherence Comparison
Date Mon, 05 Oct 2009 13:05:15 GMT
* Coherence is in-memory, Cassandra is persisted
* Coherence has a transactional model, Cassandra is eventually consistent
* Coherence has specially written adapters for different
environments/languages, Cassandra supports most languages through
* They both are distributed repositories of data written in Java

Coherence seems to be in the same write-through cache / in-memory DB
space as Terracotta or Gigaspaces, and not the distributed database
space like Cassandra.  It might be interesting to evaluate Coherence's
clustering mechanisms, but I couldn't easily find documentation.
