FWIW, Keebo (https://keebo.ai/) tries to solve this problem & reduce your Snowflake bill by using Data Learning techniques. It can be configured to return exact results or approximate results.
It is always interesting seeing companies building up on the products / services of other companies. Kinda like TurboTax built on the IRS, these "children" (is there a better term?) companies are quite dependent on the "parent" company not changing or improving its product / service.
I don't see AWS changing so dramatically that companies like DataBricks are put in hot water (but I could be wrong), but I could see Snowflake improving its product due to competition, putting Keebo in a tough situation.
By the time I reached this comment I counted no fewer than five completely separate links to offerings to help reduce your Snowflake bill. For something that is already a focused SaaS product, I have to say that starts to smell a bit.
