Support DynamoDB as TrackingModule

[cunla]

I am currently using Aurora as my tracking database. This has been working well. However, looking into the tables/queries, I think it would be beneficial to have support for DynamoDB table with msg_id as hash-key and create_dt as the range-key.

As far as I can tell, all the DB interaction is implemented in DbTrackingModule (using a DB connection from IDBHandler)

Would it make sense to create DynamoDbTrackingModule to support the same operations in DbTrackingModule using DynamoDB?

I am happy to implement this and would appreciate some pointers in terms of design choices here before I start.

I would support this as an addition.
You are on the right track in terms of implementation.

As long as your class extends BaseMsgTrackingModule and you include your new class in the config.xml as a module then tracking messages will be passed to your new class.

Please make sure you use properties for any config your class needs and default the "enabled" property to "false" for backwards compatibility.

It may be worth having a base NoSQL class that generically supports NoSQL operations that are common across NoSQL implementations if possible so that we can more easily add other NoSQL systems if desired.

I have been relatively sparse i nmy answer as it seems you hace q reasonable handle on what to do but reach out if you need more specifics about anything.

Great, please assign this issue to me.

I will create a PR and ask you to review every time I reach certain milestones to ensure I don't break the design patterns on the repo.
