Philipp Bracher commented on MAGNOLIA-1682:
-------------------------------------------
Note the 3.6 EE uses a transaction activation. Means that we guarantee that the
content reaches either both or none of the public instances. This is
recommended way for 'clustering' public instances.
Nevertheless we want to use jr clustering in future (for other shared data like
public users, comments), but for now we are 'blocked' by some critical issues.
