Your Streaming Iceberg Table
in 3 Simple Steps

Stop wrestling with complex catalog setups. With RisingWave's integrated hosted catalog, you can turn your object store into a streaming-ready Apache Iceberg table with just a few lines of SQL.

Ingest data from Kafka, CDC streams, or other sources, and let RisingWave handle the rest. Go from raw streams to query-ready tables in minutes.

-- 1. Connect to your object store
CREATE CONNECTION my_iceberg_connection WITH (
    type = 'iceberg',
    warehouse.path = 's3://your-bucket/iceberg-stocks',
    hosted_catalog = true -- No external catalog needed!
);

-- 2. Create your Iceberg table
CREATE TABLE stock_trades (
    trade_id INT PRIMARY KEY,
    symbol STRING,
    trade_price DOUBLE,
    trade_volume INT,
    trade_time TIMESTAMP
) ENGINE = iceberg;

-- 3. Stream data into your table
INSERT INTO stock_trades
SELECT * FROM your_kafka_stock_stream;

Managed Apache Iceberg™ Tables: Tailored for Your Streaming Data

RisingWave goes beyond real-time ETL/ELT for lakehouses—it also compacts data and delivers high-performance lake analytics. No vendor lock-in—your Iceberg lake is yours, and we help you integrate seamlessly with the open data ecosystem.

Ingesting and Transforming Streaming Data in Real Time

Continuously track and capture data changes from Kafka or database Change Data Capture (CDC) streams. Transform updates on the fly and seamlessly sync them to your data lakehouse—whether Iceberg or Delta Lake—ensuring fresh, query-ready data in real time, without the complexity of batch processing.

Compact Parquet Files Whenever Needed

Continuously compact Parquet files in Iceberg to optimize performance and minimize storage overhead. Maintain a fast, efficient, and query-ready data lakehouse—eliminating the complexity of manual maintenance.

Run Lake Analytics Using the Same Engine

Run high-performance analytics directly on your Iceberg lake without the need for external query engines. With built-in support for SQL-based querying, RisingWave enables seamless real-time insights, ad-hoc exploration, and complex analytics—all while ensuring optimal storage and compute efficiency. Whether you're processing streaming updates or historical data, RisingWave makes Iceberg analytics fast, efficient, and scalable.

Rich Set of Connectors

RisingWave offers purpose-built streaming connectors equipped with built-in intelligence to detect back pressure, enabling efficient data ingestion from numerous sources in a decentralized manner.

Composable Data Pipelines

Live data has short shelf life. Incremental updates are triggered automatically in RisingWave to guarantee always fresh insights letting users get the most value of their data sets.

Incremental Processing for Ultra Low Latency

RisingWave makes data pipelines composable, allowing tables and views generated by one query to be seamlessly used as inputs for downstream queries.

Native Data Lake Formats Support

Interoperability is a core design principle of RisingWave. As Iceberg and Delta increasingly become the de facto standards for data lakehouse table formats, RisingWave provides robust read and write support for both.
