Subject [jira] [Created] (CASSANDRA-7510) Notify clients that bootstrap is finished over binary protocol
Date Tue, 08 Jul 2014 06:31:38 GMT
Joost Reuzel created CASSANDRA-7510:
---------------------------------------

             Summary: Notify clients that bootstrap is finished over binary protocol
                 Key: CASSANDRA-7510
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7510
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Joost Reuzel


Currently, Cassandra will notify clients when a new node is added to a cluster. However, that
node is typically not usable yet. It first needs to gossip its key range and finish loading
all its assigned data before it allows clients to connect. Depending on the amount of data
this may take quite a while. The clients in the mean time have no clue about the bootstrap
status of that node. The only thing they can do is periodically check if it will accept a
connection. 

My proposal would be to send an additional UP event when the bootstrap is done, this allows
clients to mark the node as down/unavailable and simply wait for the UP event to arrive.

Kind regards,
Joost
