## What it is
eProsima Fast DDS is a C++ implementation of the OMG Data Distribution Service (DDS) standard with its RTPS wire protocol, serving as the default middleware for ROS 2. It enables high-performance, real-time publish-subscribe communication between distributed applications.

## Use cases
- implement pub-sub communication between distributed C++ applications
- build ROS 2 middleware with DDS
- exchange real-time data across a network with low latency
- develop robotics systems with decentralized messaging
- replace message brokers with brokerless DDS communication
- integrate DDS-compliant systems over RTPS

## When to choose
- you need a standards-compliant, high-performance DDS implementation in C++
- you are building ROS 2 applications or robotics middleware
- you need real-time, brokerless publish-subscribe with QoS control

## When to avoid
- you need simple request-reply REST APIs rather than pub-sub
- you want a managed cloud message broker
- your team works in a language other than C++ without bindings

## Facets
- artifact type: library
- maturity: stable
- function: middleware, rpc, networking, serialization
- domain: microservices, robotics, developer-tools
- platform: cpp, windows, cross-platform
- tags: dds, rtps, ros2, pub-sub, data-distribution-service, real-time-messaging, real-time, linux, macos
