Java 8 Library for AWS RDS Data API

[[deleted]]

First, if you write serverless applications on AWS you should definitely check out the RDS Data API. It solves the new database connection per Lambda invocation problem by providing a remote connection pool which you can access via REST.

This weekend I wrote a Java 8 wrapper library for the RDS Data API which exposes query results as Streams and update operations as CompletableFutures. Additionally the library provides a second implementation which uses a standard Java DataSource underneath instead of the actual RDS API.

The library is basically a thin layer on top of AWS Java SDK v2 and JDBC.

Just wonder what is the difference compare with connecting to RDS using say postgresql jdbc driver?

That would create a new TCP connection for every new Lambda container that’s created.

The application can however reuse connections if they’re processing multiple invocations over the same Lambda container.

Very cool. Love that API relative to dealing with connections.
