What type of durability EMA has?
Hi All, We subscribed for financial market data through a batch request to EMA. What happens when the update message is ready but the consumer is busy with another API call to consume some other data?

Is there a way to request all symbols for Market Price request?
Hello, Based on my understanding of UPA RDM, it seems that if I want to request market price updates for a set of symbols, I need to either send a request per symbol, or send a batch request, where in either case I have to enumerate every symbol via RDM_INSTRUMENT_NAME_TYPE_RIC. Is there a way I can instead make this…

Potential deadlock with OmmConsumer
We are creating an EMA consumer, and then opening item streams (100 items batched in each ReqMsg) with the consumer. We simply stop seeing new messages a few minutes after the consumer is established, without any exceptions or errors. This happens while the loop of opening item streams is ongoing. Debugging shows that…
