Question

I know of at least one post which has same words like this. But this is not exactly same as that post. I’m trying to work a way to “share” data between a .NET and Java application. I’m not concerned about objects, but just plain strings if u like.

I have a .NET application capturing real-time data and a Java application which has capability to analyze and work on this data. I’m looking for ways to re-use this same java app without coding it entirely in .NET.

My problem is that the data is “fairly” REAL-Time (.NET), and so has to be the analysis (Java). I can live with microsecond delays but I can’t afford one second delay. WebServices, Queues (as in Messaging Queues), RDBMS are some of the options I can think of. Is there any better way?

Or has anybody got some real performance numbers for the solutions I mentioned above to select one of them? And just to get started: RDBMSs’ are not “THAT” good for concurrent (connections doing) insertion/updation/reading, at least with the crude way of doing DBMS stuff. (Deadlocks?)

Answer 1

What are “objects” if not a mechanism for describing “data”? But I digress – I suspect I would look at a TCP socket between the two. If the data is very basic, then fine – just write directly to the stream; if there is any complexity, perhaps use something like “protocol buffers” to provide an easy way of reading/writing dense data to a stream without having to write every last byte yourself.

I think microsecond delays are going to be a challenge for any approach here… will millisecond delays do?
