tbh, databases of any kind could be used to make a chat application if your query structures are well setup etc.,.

But the feature you are mentioning like having threads could be easily be solved using like a document store ex; mongodb or any other no-sql db that could help you save time in both setting up things and querying.

Just my 10 cents.

Thanks for reply.

What do you believe is the most appropriate data-store to use and why?

(Eg relational, nosql, document, time-series, etc)
