Hello everyone, I'm currently working on a Java project that requires some service discovery and service coordination capabilities and I was thinking about using Curator for those purposes.
One of the main feature I would need is to let one service be notified as soon as another service becomes available. E.g. the service A starts and at a certain point it requires some services B. Instead of repeatedly calling the getInstance method of the ServiceProvider abstraction at regular intervals until the service B becomes available (polling-like policy), it would be nice to get notified as soon as the services B becomes available (i.e. at least one instance has been registered). Is it something feasible using something like the ServiceCacheListener ? If yes, would it be the best way to go? And, out of curiosity, what happens if the service B has been registered before the service A attaches his listener? Does the service A get immediately notified because the service B is immediately available? Thanks in advance for your help and suggestions, Fabrizio
