REST API for recursive queries

I have ~700k (and growing) domain names that should be resolved daily. I'm trying to make it efficient as possible using the recursive BIND server (do you know a better option?), the goal is to get 2000 queries per second with minimum server\s cost.
I thought using a single packet for multiple queries might be more efficient than multiple UDPs. I'll try reading more about adns to reach more queries at the same TCP connection. Any better ideas?

Do you know of a way to ask multiple DNS queries in a recursive bind server at the same packet\request? Using DoH might work? How? Is there a plugin which does that?
