ETA and EMA are TCP based UDP based libraries?

Do we need to handle package recovery if it is UDP based libraries ?

Also both libraries are available on linux and windows platform as well ?

Refer to the API Compatibility Matrix, ETA C/Java and EMA C++ support Reliable Multicast transport which exchanging messages over a UDP multicast-based network

To order to use this transport, the application must connect to Refintiv Real-Time Distribution System which is configured to support multicast connection. It relies on the Refinitiv Control Protocol (RRCP) which a reliable datagram protocol to guarantee delivery of messages between two servers.

Hello @Bhimrao.Ghule

The EMA and ETA APIs (Refinitiv Real-Time SDK or simply RTSDK) use Refinitiv proprietary connection named RSSL which is TCP based, not UDP.

The RTSDK is available in Java and C/C++ editions. The supported platforms are listed in the SDK readme file and API Compatibility Matrix document (can be downloaded here and here).
