How PlanetScale Boost serves SQL queries faster
> As rows are inserted, updated, and deleted in the database, the cache is kept up-to-date in real-time, just like a read replica. No TTLs, no invalidation logic, and no caching infrastructure to maintain.<p>This is so freaking neat. Caching is one of the harder things to get consistently right and even if this was a tool that had TTLs+API to invalidate it would be cool but not even having to worry about that is even better.<p>PlanetScale continues to be an awesome service that lets you not worry about your DB and instead focus on your application.<p>My only wish for PlanetScale would be a few more (lower) tiers. Their free tier is very generous but has a few little things (like more than 1 dev/prod branch) that aren't supported and I always feel antsy about not having a prod-like DB for qa/staging. I normally use 3 branches and the free plan only supports 2, which I think changed, I thought I used more than 1 dev branch before I started paying.<p>I have a very burst-y application (it's for events, so it ramps up a few months before the event, then is crazy for 2-7 days during, then usage drops to pretty much 0 for the next ~9 months), I'd love to lower my costs for those 9 months (I could look into downgrading to the free plan but I'd rather pay just a little less and have my quotas drop accordingly). In the end PlanetScale is still worth it for me at $360/yr so I'm not complaining too much. For smaller projects I just worry about using the PS free tier since if I go over those limits the jump is steep ($0->$30/mo), that said I might be overthinking it.
