Supported Spring Data Comparison Operators

Spring-data-dynamodb supports both findBy and queryBy repository methods in the same way:

1. It tries to build a DynamoDB QueryRequest, but is only able to do so if all properties in the method name are one of the following:

• Hash Key
• Range Key
• GSI Hash Key
• GSI Range Key

2. It will fall back on a Scan if the properties used do not fall within the list above. For scan to work you need to annotate either the class or method with the @EnableScan annotation.
