Big data is the buzzword all over lately, but fast data is also gaining traction. If you are into data streaming, then you know it can be tedious if not done right and may result in data leaks/OutOfMemory exceptions. If you are building a service or product today, users are willing to pay lots of money to those who provide content with latency of just milliseconds.
Akka Streams
Akka Streams are a streaming module that is part of the Akka toolkit, designed to work with huge data streams to achieve concurrency in a non-blocking way by leveraging Akka toolkit's power without defining actor behaviors and methods explicitly. They also help to conceal the abstraction by ignoring what is going under the hood and help you focus on the logic needed for business.
