Subject [jira] Commented: (AVRO-606) Add File-Based Span Storage to TracePlugin
Date Thu, 05 Aug 2010 18:02:16 GMT

    [ https://issues.apache.org/jira/browse/AVRO-606?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12895756#action_12895756

Philip Zeyliger commented on AVRO-606:
--------------------------------------

Pressed "add" quite early.

Looks reasonable, for the most part.  It feels a bit odd that the reader and writer of these
log directories are the same class, still.  That might be worth splitting up at some point.
 Instead of keeping a list of all previous files, you could also simply scan the directory
and look around.  Note that it's possible to add some metadata to AVRO data files when you
open them, so you might store the open time in the header.  (The close time would require
a seek...).  That way, you could retrieve spans across restarts.
