> It seems the direct use of the Database is all wrapped in a JSON-related file object, which kind of confuses me, would you mind providing a brief explanation of the class structure somewhere? Hey thanks @mbrookhart for asking! Let's focus on the database API and ignore the workload registry part (which will be removed according to previous discussion with Cody in this thread). * The base abstract class is `Database`, which has 4 pure virtual methods: `commit_workload`, `commit_tuning_record`, `get_top_k`, `size` * The system interacts with any subclass of `Database` by calling these 4 methods * To implement a concrete subclass of `Database`: in pure C++, we can just inherit Database and do so; in pure python, we provide `PyDatabase` to inherit from, where we plays some tricks, so that everything can be implemented in pure python * `JSONFile` is a simple default implementation of `Database` for open source -- This is an automated message from the Apache Git Service.
