Source postgres: fix schema permission issue #19024

sashaNeshcheret · 2022-11-07T12:23:36Z

What

Based on issue, during sync user gets permission denied for schema. Need to void using tables from schemas where user don't have USAGE permissions

How

Updatde query that fetch metadata for tables with checking USAGE permissions for schema, it fixes case when user could pick up tables from schemas without permission during discovery. But in case when permission was revoked from user between discovery and sync, all not permitted tables will be skipped without any error, but as far as it happens silently
user can be confused that number tables after sync are less than picked during discovery.

Looking at the issue, I'm not sure we want to silently fail as we're doing. If I understand correctly, in the case where:

User configures streams assc with schema they have access to
User then has access revoked from some of the schemas
User runs a sync, which appears to run successfully but data from the schemas that they no longer have access to fail

In this case, the user might wonder why records from certain schemas might be missing? But looking at this, we see that the same issue holds for table privilege.

We may want to throw a ConfigErrorException here instead

akashkulk · 2022-11-18T01:23:09Z

Related to this - am I correct in understanding that today, while calling discover() the user is allowed to choose tables from schemas that they do not have access to?

sashaNeshcheret · 2022-11-18T10:27:14Z

Yes as answering on your last question. I started to work on issue that user gets permission denied exception during sync, but during investigation i found that user can choose tables from schemas without usage permissions during discovery. Pr is fixing root cause, and as far as we run this code before sync we will not catch such exception.

For not skipping schema without permission silently we should add additional step during discovery for verifying schema permissions for all schemas that user specified during creating source, wdyt?

akashkulk · 2022-11-18T21:22:33Z

I think that makes sense. Ideally, after this change, few people will get into the state as they will be unable to choose a schema during discovery that they do not have permissions for.

It seems like we silently fail syncs today if the current user loses select privileges for a table as well? This just adds a similar failure mode to that case.

Created https://github.com/airbytehq/airbyte-internal-issues/issues/2658 to track this partial sync scenario

akashkulk

Can you add a similar test for the discover() case too (discover shouldn't be returning tables assc with schemas user has no access to)
