RisingWave

RisingWave Labs, headquartered in San Francisco and led by founder and CEO Yingjun Wu, develops RisingWave, an open-source distributed SQL streaming platform licensed under Apache 2.0. It helps companies turn event streams and database changes into continuously updated results without writing complex stream-processing code.

RisingWave ingests from Kafka, Pulsar, Kinesis, CDC of MySQL and PostgreSQL and other sources, keeps cascading materialized views up to date and serves queries directly through a PostgreSQL-compatible interface. Storage is decoupled from compute, and an Iceberg table engine with a hosted catalog lets streams land in an open lakehouse. RisingWave Cloud runs on AWS, GCP and Azure, with BYOC and self-managed options. Users include PepsiCo, Siemens, SHOPLINE, Atome, Tencent and Robinhood.

• Streaming SQL: Watermarks, windows, multi-way joins and as-of joins over live and historical data.
• Materialized views: Cascading views are updated incrementally and queried directly.
• CDC ingestion: Change data capture from MySQL and PostgreSQL with parallel backfill.
• Iceberg lakehouse: Built-in Iceberg table engine and hosted catalog for open lakehouse storage.
• Broad connectors: Kafka, Pulsar, Kinesis, Pub/Sub, S3, Snowflake, BigQuery and ClickHouse.
• Flexible deployment: Managed cloud, BYOC on AWS, GCP or Azure, or self-managed on Kubernetes.

A Vietnamese payment or buy-now-pay-later company can compute real-time fraud and risk features from transaction streams. A logistics firm can maintain live shipment status views from IoT and order events. A retailer can stream sales and inventory changes into an Iceberg lakehouse for same-day reporting.

Teams write streaming pipelines in PostgreSQL-style SQL instead of Java or Scala jobs, shortening development. One system processes and serves fresh results, removing a separate serving database. Decoupled storage, dynamic scaling and fast recovery lower operating effort, and the vendor claims up to 10x cost efficiency. The core is open source and the cloud service starts with a 7-day free trial.

Fraud detection, live pricing, logistics tracking and AI agents all need data that is seconds old rather than a day old. Companies are also standardizing on open table formats such as Apache Iceberg, so stream processing that writes directly to a lakehouse is in demand, including among fintech and e-commerce players in Southeast Asia.
