Subject [jira] Commented: (CASSANDRA-397) bootstrap and ringcache
Date Fri, 28 Aug 2009 21:33:32 GMT

Jonathan Ellis commented on CASSANDRA-397:
------------------------------------------

right -- if you need to skip the extra hop for performance, you will want to skip the extra
serialize/deserialize from Thrift, too, and you're already importing a whole bunch of Cassandra
classes so you might as well use MessagingService + StorageProxy.

> Bootstrap mode makes it easy to shoot yourself in the foot with RingCache (see CASSANDRA-197).
> One solution would be to have the node that is providing data to the new, bootstrapping
node, echo writes to the new node.  Currently, the coordinator node is in charge of including
the new node as an "extra" replica, but if a fat client is using messagingservice directly
with RingCache that doesn't work.
