Best Tools for Managing Large Data Sets: Recommendations Needed

Hey Clay team. For those of you that are data-horders, what tools are you using? Right now, I need 50K+ records saved per month. Facing issues with google sheets oauth, as too many results are queued and holding up my workflow in Clay. I was thinking of switching to Air Table, but seems like they might not be the best solution. I then started looking at Jotform tables, where it seems pretty cost effective. What solution would you guys reccomend?
