James Taylor commented on PHOENIX-808:
--------------------------------------
We could snapshot system.stats, but the data is more or less transient. Losing
it just means you have to generate stats again. If we snapshot more than one
table, it's a bit tricky to restore. What if we successfully restore one but
not the other?
> Create snapshot of system tables prior to upgrade and restore on any failure
