Subject [jira] Commented: (CASSANDRA-733) track latency in nanoseconds, not milliseconds
Date Thu, 04 Feb 2010 17:04:27 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-733?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12829649#action_12829649

Jonathan Ellis commented on CASSANDRA-733:
------------------------------------------

possibly we want to measure w/ nanotime but store in microseconds so we get more mileage out
of our Long counters (LatencyTracker & friends)

> track latency in nanoseconds, not milliseconds

> many ops finish in <1ms so presenting as ms ("0") isn't very useful.
