We are developing an application with AWS IoT Core, Lambda, and AWS RDS(db.m5.large). We process over 1000 requests per second. To optimize our connection management, we have enabled RDS Proxy for connection pooling. However, occasionally, we encounter ETIMEDOUT errors when attempting to connect to the database. Could someone provide insight into this issue?

Hi, have you tried tuning RDS Proxy's connection pool settings? https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/rds-proxy-managing.html#rds-proxy-connection-pooling-tuning
No, will try it. Thanks for sharing it. I saw another error like "Timed-out waiting to acquire database connection". is it because of same?
Yes, you might have to tune connection pool settings if this error occurs occasionally.
hi, check your security rules includes any restrictions.. also you can add the alarm from watchdog that notifies you about timeout error and restarts your RDS. also check if while getting timed out error is any of security check is failed.. Thanks
