Materialized View (RW Specific Feature)

A Materialized View in RisingWave is a core concept where the results of a continuous SQL query (defined using `CREATE MATERIALIZED VIEW`) over streaming data are automatically computed, stored, and kept up-to-date incrementally. Unlike traditional database MVs requiring manual refreshes, RisingWave MVs update dynamically with low latency as source streams change via incremental computation. This makes complex streaming results readily available for fast querying without recomputing on the fly.
