Completely fucked up replication of MySQL servers.

Remote: 2 different database Servers
--> made sense.

Except the misconfiguration. Or better: No configuration at all.

So how to solve the massiv delays and make everything even more crazy?

2 remote servers - 2 readonly slaves for reading data remote (master - slave)

2 local (internal) servers.

Remote - Local Master Master.

Unfucking this cluster fuck was a real nightmare.

It had to be done at night, cause everything needed to be ripped apart.

And the servers were the backend of a warehouse with supply chain and multiple selling channels (Amazon, eBay etcetera).

So. It had to run the next day at 05.00 clock so the incoming orders could be packaged / prepared for shipping.

That was fun. Not.

And the clusterfuck died spectaculously on my first work day - the old DBA was gone (fired....)
