This is the Real-Time SDK (RTSDK). This SDK encompasses these open source Real-Time APIs: Enterprise Message API (EMA) and Enterprise Transport API (ETA).
The Enterprise Message API (EMA) is an ease of use, open source, OMM API. EMA is designed to provide clients rapid development of applications, minimizing lines of code and providing a broad range of flexibility. It provides flexible configuration with default values to simplify use and deployment. EMA is written on top of the Enterprise Transport API (ETA) utilizing the Value Added Reactor and Watchlist.
The Enterprise Transport API (ETA) is an open source low-level Transport and OMM encoder/decoder API. It is used by the Real-Time Distribution Systems and Real-Time for the optimal distribution of OMM/RWF data and allows applications to achieve the highest performance, highest throughput, and lowest latency. ETA fully supports all OMM constructs and messages.
The RTSDK was formerly known as Elektron SDK (ESDK). Starting with version 2.0 (ETA & EMA 3.6), SDK was rebranded with the following impact: namespace changes and jar files names. This applies to applications written to EMA C++, EMA Java and ETA Java. If upgrading from a version prior to RTSDK 2.0, please alter code, re-compile and redeploy applications to pick up these changes. Please note that connectivity to products will not be impacted after rebranding and existing applications will continue to work. For more details, please see the following:
The Real-Time-SDK will support multiple languages across different combinations of Linux and Windows and their corresponding compilers. Navigate to the language and API of your choice to see the individual API README.md files for further details on building and running the API and examples. You can click on the below links to take you to the language of your choice.
Documentation is available in PDF format on GitHub and LSEG Developer Portal.
