Akka Streams
Akka Streams is a library for building reactive stream processing applications on the JVM, part of the Akka toolkit. It provides a high-level, type-safe API for composing asynchronous and non-blocking data processing pipelines with back-pressure handling. It is built on the Reactive Streams specification to ensure interoperability and efficient resource usage.
Developers should use Akka Streams when building scalable, resilient, and responsive applications that require processing large volumes of data streams, such as real-time analytics, IoT data pipelines, or microservices communication. It is ideal for scenarios demanding back-pressure management to prevent overload, asynchronous processing to improve throughput, and composable stream graphs for complex transformations.
