Auto-Discovery of Instances and Configs #388

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
A nice enhancement would be automatically discovering other voldemort instances 
and downloading a shared config.  This would alleviate the config file issue as 
there would just be a bunch of shared settings.  For example, when starting a 
new node you just need the location of one server and once connected, it would 
locate all of the other servers on the network.  This means that you wouldn't 
have to maintain a list of all servers on every host.

Also, the two config files that are static on every host (cluster.xml and 
stores.xml) would be "downloaded" from the other servers.  All of the 
information would be stored in the database.

This would make the cluster much more dynamic as spinning up a new instance 
would instantly connect and start doing work (after downloading its share of 
data).  You wouldn't have to update all of the other machines configs.

In the per-node configuration you would just have to list a number of seed 
machines so that it can connect and find the others.
