Sergio Peña commented on SENTRY-2211:
-------------------------------------
It this an improvement or just a task to review? I feel this is just a task
that may find new improvements for indexes.
> Review the index creation for foreign keys

> URL: https://issues.apache.org/jira/browse/SENTRY-2211
> Project: Sentry
> Issue Type: Improvement
> Components: Sentry
> Affects Versions: 2.1.0
> Reporter: Na Li
> Assignee: Na Li
> Priority: Major
>
> It is generally recommended to create an index which leads on the foreign key
> column(s), to support not only joins between the primary and foreign keys,
> 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.
