ERROR: SQLSTATE[HY000] [1040] Too many connections
This error happens when maximum amount of query execution happens in parallel. This not a common issue as most of the service provider are now a days providing proper mechanism to handle these type of situation.
Primary idea for developer
- First thing try to use less query until not necessary don't use more.
- Try to avoid using query in loop for better result and optimize execution.
- Avoid `*` data retrieve until necessary else just retrieve exact dataset needed for your work.
- Use storing query results as much as possible and use them as required.
- I am personally used in set structure like if you execute a query in the top and you need those data in below footer or somewhere then please wisely use the same variable data.
- Not always recommended but if possible use connection start and close when required, on that way your connection will be closed when got the data and only request next connection when required.
Share your points' on possible if I missed something.
As per the solution
Purchase good database
Good database or we can say optimized database structure also provide by the hosting provider, I won't take any name but you can find good solution.
Choose development language based on your consumer or customer base size
Not telling any programming language is good or bad but factor is programming languages are meant for best at a unique skill. So not disrespect to any one but your choice matters. How easy to maintain or not.
