Subject [jira] Commented: (CHUKWA-307) Refactor database to use lightweight scheme
Date Wed, 17 Jun 2009 22:27:07 GMT


Ari Rabkin commented on CHUKWA-307:

Even more important than changing the DB is changing the schema; the current one is tied very
tightly to the set of metrics that we currently collect for Hadoop.  It should be possible
to generate tables automagically, based on what the demux actually produces.
