It's all around the ethos of ease of use. Snowflake does a lot of smarts in the background so that you don't have the overhead of managing indexes. And not just indexes, there is just less human intervention required overall compared to something like Teradata or even a modern lakehouse.

That said, they've kind of introduced it with the Search Optimization Service, which is like an index across the whole table for fast lookups, but even that is automatically maintained in your behalf.
