does anyone know where I can found the highest value of max_connections in AWS RDS? I'm primarily interested in the db.t2 instances running MySQL. I cannot find any appropriate link about that. Thanks!!
As @error2007s states you can find it in the console, just to complete, in a more general way you have:
- t2.micro 66
- t2.small 150
- m3.medium 296
- t2.medium 312
- m3.large 609
- t2.large 648
- m4.large 648
- m3.xlarge 1237
- r3.large 1258
- m4.xlarge 1320
- m2.xlarge 1412
- m3.2xlarge 2492
- r3.xlarge 2540
Taken from here
When you go to configuration details of your RDS you will find a Parameter Group in the details. Click on that parameter group.
In that parameter group search for max_connections you will get the value.
