In the current druid code base, we have the interface DataSegmentPusher which allows us to push segments to the appropriate deep storage without the extension being worried about the semantics of how to push too deep storage. While working on #12262, whose some part of the code will go as an extension, I realized that we do not have an interface that allows us to do basic "write, get, delete, deleteAll" operations on the appropriate deep storage without let's say pulling the s3-storage-extension dependency in the custom extension. Hence, the idea of StorageConnector was born where the storage connector sits inside the druid core so all extensions have access to it. Each deep storage implementation, for eg s3, GCS, will implement this interface. Now with some Jackson magic, we bind the implementation of the correct deep storage implementation on runtime using a type variable. |
