Conflicting documentation on Metadata storage access

[pdeva]

Affected Version

0.14

Description

The diagram in the documentation here suggests the Metadata store is only accessed by the Coordinator/Overlord node:

However the documentation here (at the bottom) suggests its accessed by all the realtime processes too. By that I assume MiddleManager/Peon nodes need to have firewall access to metadata storage too.

Which one is correct?

Realtime nodes did use metadata storage directly, but they are gone now, since #7915. Tasks do not, so I believe the diagram is correct.
