RisingWave is an event streaming platform designed for agentic AI and real-time applications. It addresses the complexity and latency of traditional event streaming stacks (like Debezium, Kafka, Flink, and a serving DB) by offering a unified system that ingests, processes, and serves data incrementally with sub-100ms freshness and low-latency query responses.

How It Works

RisingWave performs incremental computation, recomputing only affected results when upstream data changes, enabling always-up-to-date materialized views with sub-100ms end-to-end freshness. It unifies ingestion from diverse sources like webhooks, databases (via CDC), event streams (Kafka, Pulsar, Kinesis), and historical storage under a SQL interface. Processed data is served from an internal row store at 10-20ms p99 latency, while long-term retention and analytical access are managed via native integration with Apache Iceberg™, including automated table maintenance. This architecture replaces complex, multi-system stacks with a single, efficient system.

Quick Start & Requirements

A quick start can be initiated with curl -L https://risingwave.com/sh | sh. Further deployment options, including Docker Compose and Kubernetes (Helm/Operator), are detailed in the quick start guide. No specific hardware or software prerequisites beyond standard system requirements are detailed in the README for basic setup.

Highlighted Details

• Unified ingestion from webhooks, CDC (PostgreSQL, MySQL), Kafka, Pulsar, Kinesis, and S3.
• Incremental computation for materialized views with end-to-end freshness under 100ms.
• Low-latency serving (10-20ms p99) via an internal row store, accessible via PostgreSQL wire protocol.
• Native integration with Apache Iceberg™ for durable storage and analytical queries, with automated table maintenance.
• Cost-efficient architecture leveraging object storage for internal state and tables, with optional elastic disk cache for low-latency serving.
