Subject [jira] Commented: (CASSANDRA-1070) Update interface to use a wrapper for various clock types
Date Thu, 20 May 2010 14:42:54 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12869622#action_12869622
] 

Eric Evans commented on CASSANDRA-1070:
---------------------------------------

bq. Only the cassandra.avpr file is changed, the genavro is not. I don't if we use the genavro
file though, can Eric Evans enlighten us?

I have a few i's to dot and t's to cross before making {{cassandra.genavro}} the canonical
source for the avro protocol. Until then, you can safely ignore it; I'll migrate over any
changes made to cassandra.avpr.

> In the latest CASSANDRA-580 patch the timestamp used for conflict resolution has been
replaced by a Clock object that can contain either timestamp or a context byte array. That
change allows for other conflict resolution techniques to be used. 
> The change can be broken out and submitted here in order to make CASSANDRA-580 more manageable.
