Hi

What kind of HA and DR are you looking for in your solution.

My experience with streams as a HA/DR solution is not really what i wanted.

HA and DR are very broad topic you need to detail out what exactly you are looking for.

If you are asking us to evaluate your current DR HA then its difficult without knowing all you requirements in detail.

Just Curious why do you have a 3rd database as a stream replication subscriber for your HA/DR ?
