This.poolCluster = mysql. This.waitingForAutoFaileOverSwitch = false To prevent any doubt, also feel free to check out an AWS-provided example that closes connections here (linked to from docs), or another one in the AWS Compute Blog here. Many applications, including those built on modern serverless architectures, can have a large number of open connections to the database server, and may open and close database connections at a high rate, exhausting database memory and compute resources. It is responsible for helping by managing connection multiplexing/pooling & sharing automatically for applications that need it.Īn example of an application that needs it is clearly mentioned in the AWS docs: The proxy is not responsible for closing local connections that you make nor should it be. The point is that your Amazon RDS Proxy instance maintains a pool of established connections to your RDS database instances for you - it sits between your application and your RDS database. Note: You can get these details from the Amazon. In the Setup New Connection dialog box, enter a name for your connection. Open MySQL Workbench, and then choose the sign beside MySQL Connections to set up a new connection. #Sqlectron aws installKeep DB resources tied up with many open connections & you'll find yourself needing more vCPUs for your DB instance which then results in a higher RDS proxy price tag.Īnd if I should close the connection, then what's the point of using an RDS Proxy in the first place? Follow the steps below to connect MySQL Workbench to your Amazon RDS DB instance: Download and install MySQL Workbench. Closing database connections is being a good database client. Connections that are not explicitly closed might not be added or returned to the pool. The rule of thumb is to open connections as late as possible & close DB connections as soon as possible. You should not leave database connections open regardless of if you use or don't use a database proxy.Ĭonnections are a limited and relatively expensive resource. Should I close the connection after executing my queries or leave it open for the RDS Proxy to handle? The RDS proxy sits between your application and the database & should not result in any application change other than using the proxy endpoint.
