Required Methods

fn remove_file( &self, file_meta: FileMeta, is_delete: bool, index_outdated: bool, )

Send a request to remove the file. If is_delete is true, the file will be deleted from the storage. Otherwise, only the reference will be removed. If index_outdated is true, the index file will be deleted regardless of is_delete.

Provided Methods

fn new_file(&self, _: &FileMeta)

Notify the purger of a new file created. This is useful for object store based storage, where we need to track the file references The default implementation is a no-op.
