Dynamically adding producers/consumers

[wasabikun]

Hello,

Does current evolution plans for the disruptor pattern (whether on
Java or C#) include the ability to dynamically add and remove
producers/consumers? How would you change the design to accommodate
for that?

Would a design based on private buffers (taken from a large array used
as a pool) for each producer/consumer end up degrading overall
performance too much, and look like yet another actor-based scheduler?

Thanks,
Vanni

Hi Vanni,

Have a look to this thread:

http://groups.google.com/group/lmax-disruptor/browse_thread/thread/3de453858ba184f0/e4fc955a030da5ab?lnk=gst&q=add+remove+consumer#e4fc955a030da5ab

The .NET version should supports the behavior described by Martin.

Hi Oliver,

By my (still very limited) understanding of the codebase, adding new
consumers to a SequenceGroup adds more event subscribers to the graph.
Would it be possible to dynamically change the graph topology by
adding both producers and consumers?

Thanks,
V.

You can add consumers with the solution developed by Martin.

For producers you just need to specify a multi threaded strategy and you can use as many publisher threads as you want, and add/remove publisher threads while the disruptor is started.

That's great Oliver, thanks.
