Do you have any sources where I can find information regarding sizing (according to traffic: events/second) and what kind of hardware do I need ? And how to build a cluster ? Any good manuals / references where to start ? ---

Hi Glenn, Welcome to this forum! I can provide a few links(I am sure there are a lot more) but the shortest answer to your question is: It depends! Basically, it depends on: - How much data do you receive? - In which format do you get the data, how complex is the parsing? - How long do you store it? - How many search requests do you get and how complex are they? - ... The best way is to start small and upgrade the cluster if the servers come to their limits.
