Subject Re: upgrading tables?
Date Tue, 12 May 2009 20:29:32 GMT
This depends on what is changed.  For example, if you add a new column to
system metrics table, then you would need to modify the
system_metrics.descriptor file to include the new column.

If you change the table partition frequency, then you might need to change
DatabaseConfig to map correctly to the table partition frequency.

What is the use case that you have in mind?

Regards,
Eric
