Why is the record count so low after conversion to InnoDB? Who should I believe: InnoDB or MyISAM? Any ideas as to what can be done to avoid loss of this many rows?
InnoDB doesn't keep a count on number of rows, like MyISAM does. InnoDB only maintains an estimate of the number of rows in each table. This is why "select count(*) from table" takes a long time on big InnoDB tables. Usually the InnoDB count will be off by 50% or so.
