[jira] [Commented] (HTRACE-376) HTrace should support nanosecond time granularities

["Colin Patrick McCabe (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HTRACE-376?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15332398#comment-15332398 ] 

Colin Patrick McCabe commented on HTRACE-376:
---------------------------------------------

One question is what effect this should have on the span JSON?  It would be easier to add a new field than to change the old time fields, if we want to keep this change compatible and do it in the 4.x line.

Another question is how span receivers would react to this change.  I can imagine that support will need to be added gradually to each one.
