It's funny to me that we still don't have incremental materialized views. All of the parts are there (export state, agg_state (forget fn name), finalize). I wonder if they're avoiding an explicit war with clickhouse or something. I do recall they mentioned they want to add this to ducklake.

Incremental MVs are ClickHouse's best feature. If DDB adds this, the last moat is distributed query execution.

Have you run into scenarios where a simple view doesn't accomplish what you require? I always feel like views do everything I want - because the speed is so great, the full recompute isn't that big a deal.

Maybe it's a bigger deal when you have multiple users/and or more repeated queries against something that's really expensive?

I've had some use cases with low latency requirements and frequent data updates. If you want to serve data on a frontend fast it's often not feasible to recompute everything every time
