-
-To implement the custom seed provider, you must implement two methods.
-One method to match the URIs it can manage and one to download backups or dumps from the given URI.
-
-Typically, the match method uses the URI scheme (the part specified before the first colon) to determine whether it can support the given URI or not.
-For example, `file`, `http`, `https` etc.
-
-The download method should implement a scheme-specific way to obtain the backup or dump and place it into a file in the supplied destination folder.
-It should then return the path of the created file.
-
-Both credentials and configurations are passed through from options specified in the `CREATE DATABASE` command.
-`ParsedSeedProviderConfig` provides a convenient way to parse and access the comma-separated configuration string.
