Stefan Egli commented on SLING-5560:
------------------------------------
I was thinking the same that something like this could be built into discovery
itself. But then again, currently I don't really know of any other use case
that does heavy operations on topology changes. Thus I'm hesitant to move that
to discovery as it might delay other listeners unnecessarily.

> While running in a cluster (or in some case non cluster setup also) Topology
> would become stable after "some" time. For e.g. in a 2 node setup by the time
> first node comes up second node might not have started so topology would not
> detect it and first node might think that second node is not there and it can
> then start assigning job for that node to current node under stable job
> processing.
> Instead of doing this just right at startup job processing should start after
> "some" delay such that topology becomes stable. This would avoid this
> unnecessary work and probably even reduce load on the master
