David Capwell commented on CASSANDRA-17002:
-------------------------------------------

did first pass of reviews; the main comment is "how should we be accessing the 
table?", this question will make clear what the partition/cluster keys should 
be.  Second question is "how costly does this get as cluster grows", when you 
have a 1k+ cluster, memory is scares so a cache of events for each instance 
could become a problem.

> Cassandra Ring state transitions should be available through a Virtual Table

> In many situations it is beneficial to see the last N Gossip state 
> transitions for debugging and other purposes. We should expose the last N 
> state transitions through a bounded Virtual Table.
