An example implementation for Spring Boot, Spring Data and DynamoDB running locally (in-memory) with a REST endpoint to interact with the database
As part of the application and tests a local in-memory instance of DynamoDB is initialised. If you want to run the application or tests in your IDE, there are binaries of the library SQLite4Java that must exist before tests are executed.
For these binaries to exist you must execute the maven command mvn compile which will place these binaries to the top-level folder native-libs. Further information and clarity on this can be found in this article.
