a) What is Pending Connection and how does it affect ?
Not sure if this throws 1033 Instance has too many concurrent requests, when it exceeds 100. How do we handle this ? Is it like we can create 250 connections but use only 100 at a time ?
b) 250 Concurrent Connections.
Should throw error Too Many Connections if it exceeds 250
c) Per app engine instance 12 concurrent connections per SQL Instance. How do we ensure that no more than 12 connections per app engine instance ?
Have gone through
But people face certain issues in that.
d) We got OperationalError: (2013, "Lost connection to MySQL server at 'reading initial communication packet', system error: 38") error when we tried a test with 1000+ requests concurrently.
We have 1500+ people(as of now and it will grow) using our system concurrently and looks like it will fail. So we are just confused if we can use Cloud SQL due to the above mentioned issues. But solutions should be available though.
