Detailed Description

Container metadata management operations in the metadata database.

This header defines function objects for retrieving, pulling, and pushing container metadata records in the metadata database. It provides a set of operations that can be used to manage container metadata in the metadata database, including support for coroutines for efficient data processing. The operations are designed to be used in a constexpr context for compile-time evaluation of metadata management operations.
