Server connection status notification to the application. #23

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I am using 2.0.2 client on RHEL and have one issue.

We have two TOMCAT servers in production and will have memcached running on
both. 
case 1. when one servers goes down client uses the other active one.(works
fine)
case 2. when both the servers goes down then we are disabling cache and
fetching data from database.(works fine)
case 3. When atleast one of the servers comes back is there any way for the
client to get notified about it. So that we can enable caching.

I could not find any solution for the above problem in case 3. so changed
the client implementation to have a broadcaster and added two more classes
as listeners. Applications who requires a notification should subscribe to
the events and hence will get the notifications.
I am not sure how to do this with the current implementation.
If there is a better way then let me know other wise I would like to
contribute to this.

Regards,
Paul.

Interesting.  I just added the ability for you to poll status in what will be 
2.1. 
It makes a lot of sense to be actively told when we lose servers, though.  I 
mean,
it's not like I don't know.

I've been doing a ton of work for 3.0, it might fit in there very well if not 
sooner.

This has been sitting around for a while.  I finally did something good here in 
what
will be 2.3.  It's only for observers, but I've been able to do things like 
block for
failures/bringups on latches and what-not.
