We've spent a lot of time building systems to keep Stacker responsive even if the underlying data source isn't.

And both of these fit that bill: the Gsheets API is generally quite sluggish, especially for large sheets, and the Airtable API only lets you fetch 100 records at a time, with no skipping pages!

We cache the responses from each API to keep reads as quick as they can be, and try our best to be smart for writes too.
