Flume is a mature system that focuses on data pipe, it can transfer data from one data source to another data source, and the system provides a large number of ready-made pipe plugin. Certainly you can also do some calculations and analysis, but the development of plugin is not convenient and fast as JStrom.

S4 is a semi-finished products, system robustness is OK, but poor data accuracy, can not guarantee the data fault-tolerant, this feature makes the S4 greatly restricted, is also the reason why few projects are using S4 since it is opened source.

AKKAis an actor model, is also a good system, based on the actor model, you can do anything whatever you want, but the problem is that you need to do everything, you should consider the topology how to generate, how to serialization, how data flows (random or group by), and so on.

Spark is a lightweight memory MR, more focus on bulk data processing, it can handle higher throughput, but more latency.
