RisingWave is the world’s most advanced event stream processing platform engineered to provide the simplest and most cost-efficient approach for processing, analyzing, and managing real-time event streaming data. It provides both a Postgres-compatible SQL interface and a DataFrame-style Python interface.

RisingWave can ingest millions of events per second, continuously join and analyze live data streams with historical tables, serve ad-hoc queries at low latency, and deliver fresh, consistent results wherever needed.

Not just a stream processor!

RisingWave simplifies end-to-end development of real-time data pipelines and applications - going beyond traditional stream processors.

Like other stream processors, RisingWave supports:

• Ingestion: Ingest millions of events per second from streaming and batch sources.
• Stream processing: Perform real-time incremental processing to join and analyze live data with historical tables.
• Delivery: Deliver fresh, consistent results to data lakes (e.g., Apache Iceberg) or any destination.

But RisingWave does more. It provides both online and offline storage:

• Online serving: Row-based storage for ad-hoc point/range queries with single-digit millisecond latency.
• Offline persistence: Apache Iceberg-based storage that persists streaming data at low cost, enabling open access by other query engines.

Key design decisions

RisingWave is designed to be easier to use and more cost-efficient:

PostgreSQL compatibility

• Seamless integration: Connects via the PostgreSQL wire protocol, working with psql, JDBC, and any Postgres tool.
• Expressive SQL: Supports structured, semi-structured, and unstructured data with a familiar SQL dialect.
• No manual state tuning: Eliminates complex state management configurations.

Zero disk architecture

• Cloud-native storage: Stores data in S3 (or equivalent), using local disk as a cache.
• High performance: Optimized for complex queries like joins and time windowing.
• Fast recovery: Recovers from system crashes within seconds.
• Dynamic scaling: Instantly adjusts resources for workload spikes.

In what use cases does RisingWave excel?

RisingWave is particularly effective for the following use cases:

• Streaming analytics: Achieve sub-second data freshness in live dashboards, ideal for high-stakes scenarios like stock trading, sports betting, and IoT monitoring.
• Event-driven applications: Develop sophisticated monitoring and alerting systems for critical applications such as fraud and anomaly detection.
• Real-time data enrichment: Continuously ingest data from diverse sources, conduct real-time data enrichment, and efficiently deliver the results to downstream systems.
• Feature engineering: Transform batch and streaming data into features in your machine learning models using a unified codebase, ensuring seamless integration and consistency.
