I'm looking into this issue where I'm trying to understand how this event queue and publishing works with respect to shared master db with 2 CM Instances & respective 2 CD instances with dedicated web database.
I'm referring to this blog post
Whereas according to blog, respective CD's Event-Queue database table register corresponding CM instance details from where the request initiated.
I need help to understand how event-queue and publish queue is initiated from CM to CD. Have anyone came across this scenario. Please help. Thanks.
