---------------------------------

             Summary: Low Level Documentation for Sling Discovery.
                 Key: SLING-5021
                 URL: https://issues.apache.org/jira/browse/SLING-5021
             Project: Sling
          Issue Type: Wish
          Components: Documentation
            Reporter: Ian Boston
            Assignee: Stefan Egli


Improve the documentation at:

https://sling.apache.org/documentation/bundles/discovery-api-and-impl.html to 
include details on:

Conceptual Structure of a topology (eg Topology contains Clusters contains 
Instances).
Definition of a Cluster.
Description of the Voting process.
Description of how topology uses the following areas of a repository
{code}
/var/discovery/impl/clusterInstances
/var/discovery/impl/establishedView
/var/discovery/impl/ongoingVotings
/var/discovery/impl/previousView
{code}
What writes to those locations.
How instances within a cluster communicate.
How instances within a topology communicate.

This information will help anyone faced with dealing with low level failures 
related to topology in live running instances and may enable them to configure 
to avoid those failures. Improved documentation in this area will be greatly 
appreciated.
