---------------------------------
Summary: Add Topology Message Verification to the Discovery
service.
Key: SLING-3154
URL: https://issues.apache.org/jira/browse/SLING-3154
Project: Sling
Issue Type: Improvement
Components: General
Affects Versions: Discovery Impl 1.0.0
Reporter: Ian Boston
Assignee: Ian Boston
Fix For: Discovery Impl 1.0.2
The discovery service provides support for whitelisting sources of topology
information, but in a cluster where the topology this creates a
re-configuration load of order M*(n*(n-1)) where n is the number of nodes in
the topology and M is the number of changes. That load rises rapidly as the
number of changes and/or nodes increases.
To address this there are 2 proposals.
1. To provide an SPI exported from the Discovery Impl bundle that allows
implementors to implement whitelisting based on the request. This will need to
support creating the request and validating the request.
2. Embed functionality within the Discovery Impl bundle that supports
validation and encryption of topology requests.
