> Issue Type: Task
> Components: Sentry
> Affects Versions: 2.1.0
> Reporter: Na Li
> Priority: Major
>
> It is generally recommended to create an index which leads on the foreign key

> but also updates and deletes.
> We should review the foreign keys and check if there is an index defined, if
> not, should we create index.
