Hi,
Client is receiving EMA data - update/refresh. How best they can store these data? Are there any tables / template available so that client can reuse them?
Thanks

Hello @Raghava.B S
The ESDK 1.3.1 (EMA Java/C++ version 3.3.1) now supports the clone feature that lets you clone and copy EMA messages to decode the payload outside of message callbacks.
Example functions are following:
- EmaFactory.createRefreshMsg(RefreshMsg other)
- EmaFactory.createUpdateMsg(UpdateMsg other)
Please see more detail in EMA C++ Reference Manual and EMA Java Reference Manual in Development Guides document.
I also suggest you check the following posts which give you additional detail regarding cloning the message.
- https://community.developers.refinitiv.com/questions/54380/serializedeserialize-messages-in-ommconsumerclient.html
- https://community.developers.refinitiv.com/questions/48476/when-processing-updatemsg-using-multiple-threads-k.html
However, if the client wants to keep only data, the client needs to extract the payload and transfer into data store like database,file as my colleague have mention above.
Hi, Wasin, so EmaFactory.createRefreshMsg and EmaFactory.createUpdateMsg are only for Java ? I could not find such names in EMA C++ SDK. So is there equivalent functions in C++ SDK ? Many thanks

Hello @Raghava.B S
EMA retrieves real-time data and passes data to the client application as is. It does not provide any tables/template to store data. The clients need to implement this by themselves. The suitable way depends on the client requirements e.g. keep in database or file.

Hello @wangfugen
For EMA C++, the equivalent functions are available in each Refresh/Update/Status ... Message classes under thomsonreuters::ema::access Namespace. Please check EMA C++ Reference Manual Guide document under EMA C++ Development Guide page.
