Open Table Format

An Open Table Format (e.g., Apache Iceberg, Apache Hudi, Delta Lake) defines specifications for organizing and managing large analytical datasets stored in data lakes (like S3, GCS). They bring reliability features like ACID transactions, schema evolution guarantees, time travel, and performance optimizations (partitioning, compaction) directly to lake storage, enabling Data Lakehouse architectures. RisingWave can integrate with these formats, particularly Iceberg, as sinks for building real-time lakehouses.
