Hello, I am building a big web application that I want to be massively scalable (I am using cassandra and titan as a general db).
I want to implement the following: real time web chat that is persisted so that user a in the future can recall his chat with user b,c,d much like facebook. mail like messages in the web application (not sure about this as it is somewhat covered by the first one) user activity streams users subscribing to topics for example florida/musicevents Could i use kafka for this? can you recommend another technology maybe?
