Review comment:
Could this be handled better? It seems that in the event of an
exception, the entirety of the in-progress snapshot would excluded.
Logging the exception doesn't tell us anything useful because the
`SnapshotDescription` isn't party to the message. Maybe we should log the
snapshot name and table name. At WARN level?
