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. (obviously, this category is the biggest one), SQL code formatting, and Productivity enhancements. 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: Lets compare the code completion capabilities of two high-end SQL Server database tools: Azure Data Studio and dbForge SQL Complete. The proxy is not responsible for closing local connections that you make nor should it be. Use Azure Cosmos DB SQL Studio to render spatial data on a map by using the Map tab. To visualize the data, define the x-axis and y-axis with two dropdowns. This uses the Poor Mans T-SQL Formatter to format your T-SQL inside Azure Data Studio/SQL Operations Studio. The data Analyzer tab will help you with simple analysis requirements. 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. This can be a challenge since returned data is in JSON format. Keep 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? Closing database connections is being a good database client. Azure Cosmos DB SQL Studio is a free VSCode extension you can download directly from the VSCode Extensions tab or the VSCode Marketplace website. 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.
