View as plain text  

I have a cluster with 2 API/SQL nodes and 1 managernode. Version used is 5.1 (7.09
The data nodes have 16G Memory

Among other things I use this  as a service backend for my mailscanner gateways.
They use spamassassin MySQL based. This I have implemented as a NDBCLUSTER DB but
I have terrible performance problems using this.

The estimates size of the DB is around 4G. The table I query has around 25 Million
So should I go back and use InnoDb for this as I did in my prior setup or do anybody
have some tuning recommendations.
