So true on the mySQL part ... and indeed he is missing the whole point.

He also mentions, power consumption. Anybody anything to say on that when
comparing one large server (with storage etc) against a "comparable size"
cluster? 

I read somewhere about a company building rack mountable servers based on
miniITX boards, putting 2 cards in one housing. When each of them is
equipped with a high efficient PSU, the wattage should be extremely low. Or
maybe something like this (http://www.mini-itx.com/projects/cluster/) for
DIY use?

I wonder, if you never have found the need for bigtable-like data
storage system, maybe you've just never had the problem?

So one thing he is forgetting is that all the things he derides
'nosql' databases for eschewing, we _already avoid them on mysql right
now_ due to scalability problems!  Joins, indexes, schemas,
transactions are all mysql features that cause problems at scale, yes
even with innodb. Or especially with innodb perhaps?

Apparently Google has a 44PB bigtable instance, my particular
challenge to mr Aker is "how would you use mysql or drizzle to store
44 PB in an unified manner?"   ie: no after-the fact sharding
(cheating imho).

Then there is the hardware scalability problems with databases...
maybe he's ok with $500,000 machines. We are not.

I just see this talk as "old guard derides the new kids for lacking
all the awesome features we have".  Particularly ironic since myisam
kind of sucks and mysql has traditionally been
anti-transactions/foreign keys. Obviously times change since mysql
supports all those features now, but I just view it as mysql becoming
the establishment database like oracle.
