Just use LVM striping. If it turns out to be an issue; that seems to be mostly conjecture. I note that the SSDs are only instance storage. The data will be gone when the instance goes away. I have used instance storage in replicated setups but it always feels rather fragile unless your data really is transient or you can maintain 2 replicas. Their other new service, provisioned IOPS for EBS, might be more useful for a persistent database. Although not nearly SSD speeds, of course. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
