> No built-in cross-database querying, making complex analytics difficult without a dedicated data lake

I've looked at Turso before and this is exactly what came to mind. I do see some use cases where it could work, but for most real-world applications, this is an absolute red flag that shouldn't be overlooked.

This seems to be the biggest hesitation I've heard over and over by far. There absolutely needs to be a good story here for both (a) ad-hoc cross-partition queries and (b) automatically building a datalake without having to know what ETL stands for.

However, this isn't so much different from Cassandra/DynamoDB which have a similar problem. You _can_ query cross-partition, but it's strongly discouraged and will strain any reasonably sized cluster.
