It's not replicated (yet) and uses Durable Objects under the hood, so it's single-threaded and has a soft limit of 1,000 requests per second. It won't be able to handle 100k concurrent users.
Even though I liked what the guy said about cynical comments, marketing people are using every social engineering thing they can to make you buy their , this is equivalent to scam.
Hello, I understand that D1 is known for its excellent performance and scalability, but I'm uncertain about its performance. Do you know where I can find comprehensive information about the performance of writes and the locking mechanism when executing (whether it uses file locks, table locks, record locks, etc.)? If you know of any resources where I can find consolidated information, including findings from official documentation and other blogs, please let me know.
There's no read replication yet so I wouldn't say it's know for it's excellent read performance. Or at least, it should not be known for that (right now, we'll see what happens in the future)
