Subject [jira] Commented: (CASSANDRA-397) bootstrap and ringcache
Date Fri, 28 Aug 2009 17:12:32 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-397?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12748905#action_12748905

Sandeep Tata commented on CASSANDRA-397:
----------------------------------------

Doesn't RingCache just get data from cloneTokenEndPointMap() ?  So fat clients won't see the
Bootstrapping node until it finishes. What am I missing?

> 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.
