I've not used Coherence, all I know if from reading the first paragraph here http://www.oracle.com/technetwork/middleware/coherence/overview/index.html and wikipedia:)
Cassandra is not a caching layer, it's a database. You can rely on it as your database, and some people find when they do they no longer need a caching layer. If you can provide some more details on your use case we can help you judge if cassandra is a good fit. Or if you can tell us which features of Coherence you think are a good fit for you we can see if there are Cassandra equivalents. And is should also say: - cassandra is free - if you have a good idea about how it can be improved, there is a chance it may get implemented. And if you can provide some dev time an even better chance. - you can get free support from the community - there are multiple professional services companies that provide support http://wiki.apache.org/cassandra/ThirdPartySupport Hope that helps. ----------------- Aaron Morton Freelance Cassandra Developer @aaronmorton http://www.thelastpickle.com On 18 May 2011, at 10:44, Karamel, Raghu wrote: > Hi, > > I am new to Cassandra and very excited with the technology.
