High Availability is a complex topic and this project is add HA elements step by step:
##Overview:
- use master/slave Redis configurations
- use redundant adapters. You can start 2 or more adapters with the same name, and only one is active (check NodeStart.js swarm to see how). We are working on adding monitorization on nodes and to activate redundant nodes when the master node is not available
- we are re-sending swarms that were sent to channels without subscribers (we drop those swarm after an hour, mean time we exponentially try to resend from time to time that swarm)
- [experimental] you can put meta information in a swarm to require confirmation that a swarm was successfully executed (not only received, but executed)
- we know that more work have to be done in this area
