Operator vocabulary

Reactor provides a wide range of operators. These operators allow us to select, filter, transform, and combine streams. The operations are performed as a workstation in a pipeline. They can be combined with each other to build high-level, easy-to-reason data pipelines.

Reactor has been adopted in Spring Framework 5.0 to provide reactive features. The complete project consists of the following sub-projects:

• Reactor-Core: This project provides the implementation for the Reactive Streams API. The project is also the foundation for Spring Framework 5.0 Reactive Extensions.
• Reactor-Extra: This project complements the Reactor-Core project. It provides the necessary operators to work on top of the Reactive Streams API.
• Reactor-Tests: This project contains utilities for test verification.
• Reactor-IPC: This project provides non-blocking, inter-process communication. It also provides backpressure-ready network engines for HTTP (including WebSockets), TCP, and UDP. The module can also be used to build microservices.
