Subject [jira] [Commented] (CASSANDRA-3227) cassandra-cli use micro second timestamp, but CQL use milli second
Date Mon, 19 Sep 2011 15:27:09 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3227?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13107897#comment-13107897

Sylvain Lebresne commented on CASSANDRA-3227:
---------------------------------------------

Works for me but more because "we either do it now or never and leaving it to milliseconds
would really sucks" than out of sheer enthusiasm towards the idea.

As for the patch, I'm not too sure about this clientState.getTimestamp(). A clientState is
a potentially a long leaving object, it lasts as long as the connection to a given client
last. Since the patch only initialize to the current time but then update by +1 on every call
disregarding of the actual time, it seems the timestamp will get completely desynchronized
quickly. Or am I misunderstanding this ?

or update operation set milli second timestamp by AbstractModification.getTimestamp.
> If you register data by cassandra-cli, you can't update data by CQL. Because CQL timestamp
is judged as past time.
