Gavin McDonald updated OAK-8593:
--------------------------------
Description:
Currently, if Oak is initialized with read-write access to the DocumentStore
(Mongo/RDB) e.g through oak-run, it is made visible to upper layers (e.g. sling
discovery) via the oak discovery cluster view. This can cause problems in the
actual cluster with the differing topology view and the capabilities advertised
and in some circumstances being made a leader.
In an offline discussion with [~mreutegg] and [~stefanegli] it was decided that
its best to expose a flag {{invisible}} in the cluserNodes collection/table
with which these instances can connect and then these would be ignored by the
oak discovery.
