I have a project where the master table will have 30-100,000 rows. Nightly batch for about 1/20th of the total row count. Light online traffic.

Wondering if MySQL will scale this far. I have found a lot of performance numbers, but no indication of scalability.

The TCX guys boast about having DBs with millions of records, so you shouldn't find scalability at this level a problem.

I've used MySql with a table that has 250,000 and, for a while at least, we were transfering the entire table nightly. We had problems, but NOT due to MySql. It sounds like MySql will scale just fine for your project.
