I have been looking at different event store solutions. So far I'm torn between EventStore and plain old SQL (looking at Postgres with CitusData sharding), although this approach will require a lot of extra systems that needs to we written costing me type and money...
My main question is, has EventStore been battle tested in production? What's the average setup that companies run in production and what is their average load (read and write per second) on their setup?
Something else I'd like to ask is, what kind of stability can I expect on the Mono port? Are there plans to move to dotnet core?
Thanks in advance.
