Apache Paimon is a lake format that enables building a Realtime Lakehouse Architecture with Flink and Spark for both streaming and batch operations. Paimon innovatively combines lake format and LSM structure, bringing realtime streaming updates into the lake architecture.
Background and documentation are available at https://paimon.apache.org
Paimon's former name was Flink Table Store, developed from the Flink community. The architecture refers to some
design concepts of Iceberg. Thanks to Apache Flink and Apache Iceberg.
