State Store (RisingWave) (RW Specific)

The State Store in RisingWave is the component responsible for persistently managing the internal state required for stateful streaming operations (like joins, aggregations, and materialized views). It primarily utilizes Hummock, RisingWave's cloud-native LSM-tree based storage engine, which leverages durable object storage (like S3). The State Store ensures state durability, enables fault tolerance via checkpointing, and provides efficient state access for compute operations.
