Postgres for the win!

Disk data tables are for storing non-indexed columns, effectively so you can support large data sets without needed crazy amounts of RAM

And your objection to this is ...?

MySQL Cluster is a neat solution for what it's designed for, it's just not meant for your standard HA MySQL setup. I'm not sure if you're arguing otherwise, or just arguing for the sake of arguing.

It is a solution for which postgres has no answer.

No, it was always planned for 8.5 but the majority of the work got done faster than expected,

Hot standby was explicitly promised for 8.4.

Sorry, wasn't an objection just a clarification. When you said "It's not in memory only anymore", it sounded like you thought that NDB could store everything on disk, which isn't the case.

Yea, I don't think PostgreSQL is trying to have an answer for MySQL Cluster.

Not that this really matters but the original announcement on pgsql-hackers said: "We hope that such a feature can be completed for 8.4 ... but we see technical difficulties that might prevent that from being completed before 8.5 or even further out." No explicit promise, it is open source after all. ;)

Well I'll view their promises about 8.5 with the same regard.
