Subject [jira] Created: (CASSANDRA-1518) remember ring state between restarts
Date Sat, 18 Sep 2010 21:16:33 GMT
remember ring state between restarts
------------------------------------

                 Key: CASSANDRA-1518
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-1518
             Project: Cassandra
          Issue Type: New Feature
          Components: Core
            Reporter: Jonathan Ellis
            Assignee: Brandon Williams
             Fix For: 0.7.0


default behavior should be to remember the nodes we've seen before.  we're already storing
ip/token pairs in systemtable, but we're not removing them when removetoken is issued.

we probably want to leave some trace of nodes-that-used-to-participate-but-were-removed, but
instead of having a historical track in systemtable let's just add something to the gossip
listener in StorageService that logs token when a node comes up.

finally, there should be a flag (-D?  config?) for bringing up a node in don't-assume-anything-about-the-ring
mode as a fallback in case we run into more funky token-related bugs.
