- RF is 1. We have few KeySpaces, only this one is not replicated - this data is not that very important. In case of error customer will have to execute process again. But again, I would like to persist it. - Serializing data is not an option, because I would like to have possibility to access data using console - I will keep row cache - you are right, there is no guarantee, that my data is still in Memtable
I will get my hardware soon (3 servers) and we will see ;) In this worst case I will switch my session storage to memcached, and leave all other data in Cassandra (no TTL, or very long) Another questions: - Using Cassandra to build something like "HTTP session store" with short TTL is not an anti-pattern ? - There is really no way to tell Cassandra, that particular Key Space should be stored "mostly" in RAM and only asynchronous backup on HDD (JMS has something like that)?
