Subject [jira] Commented: (CASSANDRA-1546) (Yet another) approach to counting
Date Mon, 27 Sep 2010 19:36:33 GMT


Jonathan Ellis commented on CASSANDRA-1546:

What worries me isn't the streaming per se so much as the switching of "master" nodes when
a new node assumes responsibility for a counter row.  For normal data, we add the new node
into the CL requirements and everything Just Works.  Here, it seems like we need an extra
step post-bootstrap to make sure the new "master" is current on operations that happened during
streaming.  (1072 has the same problem.)
