Hi ,
As I have production experience in MySQL for 5+ years, I think I can solve this issue. And, I myself wont accept money if I am not able to solve the issue.
Few queries I would like to put before you accept this bid:
* Which MySQL version are you running on?
* Where is the server deployed, like bare metal or some cloud ?
* Are you ok with query changes if required for optimization?
* Are you ok with a application downtime if required for the maintenance of tables?
* What is the current database size and the capacity of the host it is running on?
* What is the TPS on the database, read and write?
