// But modules/indexer/issues has already imported models/issues to do UpdateRepoIndexer and UpdateIssueIndexer.

// And to avoid circular import, we have to move the functions to another package.

// I believe it should be services/indexer, sounds great!

// But the two functions are used in modules/notification/indexer, that means we will import services/indexer in modules/notification/indexer.
|

// So that's the root problem:
|
|
// The notification is defined in modules, but it's using lots of things should be in services.
