We have been running PlanetScale as our production database for about 6 months, migrated from Aurora Serverless. I love it, their query insights tool has been a game changer for us and has allowed us to optimize a ton of queries in our application. Their support is always available and highly technical.
For a sense of scale, we have ~150gb of data running around 5 trillion row reads + 500 million row writes per month
From what I understand your webserver and php implementation is stored on different servers from PlanetScale's DBs(?)
Just wonder: How are the DB queries from your php implementation to the Planetscale DBs affected by network latency (hops and length between servers) as well as bandwidth (query results returned by PlanetScale DBs)?
