Re: Performance trouble at 35M rows

My solution was not to use MySQL, or reduce number of rows. Reducing number of rows was not an option so I had to migrate to Oracle.
I have tried using hash instead of B-Tree for indexing. Hash was faster in indexing but query time went up (unacceptable). I think there is an implied limit around 10M rows per table for indexing. Performance degrade exponentially with number of rows (it is CPU bounded and not memory or disk). I haven't tried InnoDB and I will try that.
Even though I like MySQL for most jobs, I am reaching to a conclusion "not to use MySQL for very large tables".
