Re: Example of Cluster SLOWER than InnoDB -- help?

John,

a power outage can crash all NDB nodes at the same location at the same time, unless you use an uninterrupted power system.

On the other hand, if you use a disk drive with a battery-backed disk cache, then fsync() is very fast and the penalty of running with

innodb_flush_logs_at_trx_commit=1

is small. Thousands of commits per second should then be possible.

Best regards,

Heikki
