As an example, I tried to find a database which could support

	client-server architecture, client and server
		on separate computers
	8 million records
	ten byte unique key, ~50 byte records
	8500 probes per second, most of which would fail
		to find a matching record, so would
		plumb the entire depth of the database
	automatic fail-over to another server when server goes down
	fail-over must take place in 10ms or less
	database can be updated at rate of 100+ records
		per second while actively being probed
        
Alpha VMS & the Rdb database (purchase by Oracle from DEC back in
1994) can *easily* handle this.

It'll cost you, though
      
I'm not going to go into details, because that wouldn't be
fair to them. And I'm sure that Rdb is a fine DBMS. But
Rdb was one of the systems I evaluated in about 1998 or so.
    

1998, huh?  It could be done back then.  A co-worker was at ATT
Wireless back then and they used Rdb for their billing system.
Lots of inserts, lots of reads.

Needed (and needs) lots of expensive h/w, though.
Buy a mated pair of Tandems. In addition to wondering what 'fail over' was, you could update the OS on the fly. :-)
