I have a branch that adds streams support to the Tables class with associated tests etc.
DynamoDB Streams

The issue I am having is that adding the support to the class violates the PMD CyclomaticComplexity rule threshold of 10 (with a count of 13). I don't want to disable the rule but I can't see any way to move past this issue without a great deal of work in rewriting the Tables class etc.

Any suggestions would be greatly appreciated.
