Materialized views are not free. Each incremental view attached to a table must run its SELECT on every insert, and each execution creates a new part in the target table. Attaching too many views — more than 50 is typically excessive — will slow inserts significantly, both from the compute overhead of running each view and from the part pressure generated across all target tables. This can cascade into the "Too Many Parts" issue discussed earlier. Where possible, consolidate views that perform similar transformations, and consider whether the setting parallel_view_processing can help by running views concurrently rather than sequentially.

Anyway, outside of the blues and the avant-garde, most Western musicians just live with everything being a little out of tune. If you’re a guitarist, you know that no matter how you tune your guitar, it won’t stay in tune for long anyway, so how much does any of this even matter? There’s a joke among guitarists: we spend half our lives tuning, and the other half wishing we were in tune. There are lots of reasons why tuning is hard: you might be hampered by having a poorly made guitar, or by having a guitar that’s not set up correctly, or by using old worn-out strings, or by changes in temperature or humidity, or just by a lack of patience or time. At least you can be secure in the knowledge that some of your tuning struggles are due to the basic unfairness of the universe, and not just the limitations of your ears or your equipment.
