Amazon S3 Object Lambda
We do this all the time already when we write various interface services to access a common data store.  Each service provides whatever interface is appropriate and performs any desired transformations.It's not clear to me what the real benefits of Object Lambda provides.  Indeed it could move your transformation code closer to its data, but the cost of doing that is the management and complexity of the lambdas.  I am curious what a best use case example would be for this.
