OSS streaming database with Postgres-compatible SQL for streaming and incremental materialization. Apache-2.0. Distributed cloud-native architecture, separates compute and storage. Strong fit for real-time analytics where SQL-on-streams is the abstraction.
RisingWave is an OSS streaming database with Postgres-compatible SQL for streaming + incremental materialization — Apache-2.0 license. Distributed cloud-native architecture with separated compute + storage. Pick RisingWave for real-time analytics where SQL-on-streams is the abstraction and Flink's complexity isn't justified.
RisingWave's positioning is streaming-as-database: incremental materialized views update as streams arrive. From a Trust Before Intelligence lens, the trust insight is data freshness as a guaranteed property of the materialized view abstraction — agents query views and get current state automatically. Trade-off: newer than Flink; smaller production track record.
Sub-second incremental views.
PG wire protocol — full SQL on streams.
PG-compat RBAC. Cap rule applied.
K8s-native, multi-cloud.
Schema metadata + materialized view lineage.
Query stats + system catalogs.
PG-style governance. 1/6 -> 3.
Prometheus + per-MV cost. 3/6 -> 3.
Multi-cloud + K8s. 5/6 -> 4.
PG metadata. 1/6 -> 3.
Storage durability. 5/6 -> 4.

Compliance certifications
OSS Apache-2.0; Cloud signs BAAs.
Use with caution for
Flink for production-mature stream processing. RisingWave for SQL ergonomics.
