What is the Rate limit for Wix-Data requests per second?

I can’t find an answer anywhere, I’m developing an online event platform and I created a “chat” module using wix-realtime where people watching the event live stream can interact with each-other.
But I need to log all chat messages sent, so on my backend I’m wixData inserting all messages sent to a database to download after the event is finished. I’m worried about the rate limit for those insert requests as I’m expecting over 5.000 people simultaneously. Also I don’t know if there’s any rate limit for the wix-realtime.
Thank you for your time! :smiley:
