Eclipse LunaDDS

Eclipse LunaDDS builds upon the DDS (Data Distribution Service) standard, offering targeted improvements to Eclipse CycloneDDS. Its primary goals include:

CycloneDDS Extensions

• Zero-copy inter-process communication for improved middleware performance.
• Inter-thread communication for efficient data exchange within applications.
• Cross-machine communication over Ethernet.
• Rust Pub/Sub API for modern language integration (planned) .
• Supported target platforms: QNX 7, x86_64 Linux, and aarch64.
• Bazel build system for scalable and reproducible builds.
• Performance optimizations, including memory mapping using huge pages, lock-free data access patterns, optional bypass of the standard DDS data path to reduce serialization overhead for critical applications.

IDL Code Generator

• A flexible toolset designed to simplify service definition and code generation:
• Generates RPC-style proxies and skeletons using Jinja2 templates.
• Provides familiar method-call semantics for automotive developers.
• Supports automatic type conversion between IDL and C++ (e.g., Boolean → bool).
• Enables file-based service definitions with a simple syntax.
• Offers customizable output directories.
• Includes robust error handling and validation.Supports complex data types and method signatures.
