Configuration management for Drops.Relation.

This module handles configuration for relation modules, including:

• Default plugin configuration
• Schema module naming conventions
• Repository settings
• Function-based configuration values

Configuration Options

Configuration can be set at the application level:

config :my_app, :drops,
  relation: [
    default_plugins: [
      Drops.Relation.Plugins.Schema,
      Drops.Relation.Plugins.Reading,
      Drops.Relation.Plugins.Writing
    ],
    ecto_schema_module: &MyApp.CustomSchemaModule.for_relation/1
  ]

Function-based Configuration

Configuration values can be functions that receive the relation module as a parameter, allowing for dynamic configuration based on the relation being defined.
