Hi I plan to use zookeeper for coordinating. And my system need answer requests in less than 1 second. And need transfering data between machines. I wordering if i can use zookeeper for data transfering like this:
if machine A wants to say "hello" to machine B, we create two Znode in zookeeper: queue/a and queue/b. A write "hello from A" to queue/b first, B is listening on queue/b and can get the message, then B handles "hello form A" and write "got it" to queue/a. then A knows that the message was sent successfully. Will this as fast as socket messages directly between machine A and B? And if i have a zookeeper cluster with 5 servers, will the message "hello from A" be send to all these 5 machines? Is ZKClient on machine B get the event after the message was synchronized on these 5 machines? many thanks!
