Refinitiv Real-Time SDK - C/C++
Refinitiv Real-Time SDK APIs: C/C++ Edition
This is the Refinitiv Real-Time SDK (RTSDK), formerly known as Elektron SDK (ESDK). This SDK encompasses these open source Real-Time APIs: Enterprise Message API (EMA) and Enterprise Transport API (ETA). Please note that ETA is the rebranded Ultra Performance API (UPA). This SDK is available for download in the download section and contains pre-built libraries on support platforms and compilers. This SDK is also availble on GitHub with instructions to build the libraries.
IMPORTANT Rebranding Annoucement: Starting with version RTSDK 2.0.0.L1 (same as EMA/ETA 3.6.0.L1), there are namespace changes and library name changes. Please note that all interfaces remain the the same as prior releases of RTSDK and Elektron SDK and will remain fully wire compatible. Along with RTSDK 2.X version, a REBRAND.md is published to detail impact to existing applications and how to quickly adapt to the re-branded libraries. Existing applications will continue to work indefinetly as-is. Applications should be proactively rebranded to be able to utilize new features, security updates or fixes post 2.X release. Please see PCN for more details on support.
Enterprise Transport API
The Enterprise Transport API (ETA) is the open source, high performance, low latency, foundation of the Refinitiv Real-Time SDK. This API allows applications to achieve the highest throughput, lowest latency, low memory utilization, and low CPU utilization when publishing or consuming content. All Open Message Model (OMM) content and domain models are available through the Enterprise Transport API. ETA, written in C, is actually 3 APIs packaged as one: applications may be written directly to the transport layer (RSSL) which implements the Refinitiv Wire Format (RWF), or, to Value-Add Reactor layer, and, may optionally utilize the extensive Watchlist feature-set.
The Transport API is used by both Refinitiv Real-Time (formerly Elektron) and Refinitiv Real-Time -- Optimized (formerly Elektron Real-Time Cloud) for the optimal distribution of OMM/RWF data. ETA was formerly known as Elektron Transport API and Ultra Performance API (UPA). Please note that all interfaces in ETA are the same as their corresponding interfaces in UPA (same name, same parameter sets) and the transport and codec are fully wire compatible.
Enterprise Message API
The Enterprise Message API (EMA) is a open source, data-neutral, multi-threaded, ease-of-use API providing access to OMM and RWF data. As part of the Refinitiv Real-Time Software Development Kit, or RTSDK, the Enterprise Message API allows applications to consume and provide OMM data at the message level of the API stack. The message level, written in C++, is coded to Enterprise Transport API and fully utilizes the transports, codec, messages, data format, value-add reactor and watchlist features of ETA.
