Hello,
I am searching for a pattern that occurs quite often in EAI but I have
not found it in the list of documented patterns.
I want to process input from an external source and feed it into a
queue. To make the scenario fault tolerant at least two adapters have to
be installed on two separate machines. They read input from a custom
source (in my case I have to connect to a legacy system via an API and
subscribe to a feed). The catch is the at any time only one of the
adapters may be active.
One way to achieve this is sending heartbeats on a topic and having a
rule which adapter should be active. At the moment I start all adapters
inactive and give them a weight setting. Now if an adapter receives no
heartbeats or only heartbeats from adapters with lower weights it will
activate.
While I probably can implement this on my own I am wondering if someone
has already solved the problem.
Does servicemix provide any support for this? Or do you know any good
implementation?
Best regards
Christian
