Notification for new subscriptions Mathias

Hi Mathias, 

As Paul pointed out, what you would really want is DQPublisher for C#, but unfortunately there isn’t one at the moment. The reason for this is that that previously there hasn’t been a real demand as most C# applications have been on the client subscribing side, not the publishing side.

It sounds like there are a least a few people now looking for one so I’d be interested in finding out if there are others out there looking the same and if anyone if willing to contribute code in this are? 

Also to clarify:
The MamaPublisher  “basic" publishing ie. without sequence numbers, initial images/recaps etc or any other market data/data quality type features. The equivalent class on the subscribing side is MamaBasicSubscription.

The MamaDQPublisher and associated classes have sequence number injection, callbacks when a client subscription is made etc. The equivalent class on the subscribing side is MamaSubscription.

Cheers,
Glenn

From what I recall there, are no .net wrappers for the DQPublisher as yet (although somewhat unfairly there are in the Java codebase!). For me as a greenfield application, it was simpler to write in C++, but I think adding those wrappers wasn’t too big a deal as they were really just wrappers along the lines of the existing code for the normal publisher.

Hi,

 

Currently, I am trying to set up a publisher for market data with OpenMAMA in C#.

I wonder if there is a way to receive a notifcation every time my publisher accepts a new subscription from a subscriber? Is there an event thrown that I can handle?

 

Also, I still don't completely understand the difference between a basic publisher and an advanced publisher. In the development guide, the latter is only mentioned but never described in detail (e.g. how to use it).

 

Best regards

 

Mathias
