WILMINGTON, DE — The Apache Software Foundation announced that two open-source projects, Apache Gluten and Apache Polaris, have been promoted to Top-Level Project status within the organization.
The designation marks a milestone for the projects after completing the Apache Incubator process, which provides mentorship and oversight for developing open-source communities and governance structures.
Apache Gluten is an open-source middle-layer plugin designed to accelerate workloads in Apache Spark SQL and DataFrame operations.
According to the foundation, the software allows compute-heavy Spark tasks to be offloaded from the Java Virtual Machine to native processing engines such as Velox or ClickHouse.
The project’s architecture is intended to support integration with other Apache projects, including Apache DataFusion.
“Graduating to an Apache Top-Level Project represents an important step forward for Gluten,” said Weiting Chen, project management committee chair for the project.
Apache Polaris is an open-source catalog system for Apache Iceberg that implements Iceberg’s REST application programming interface.
The project enables interoperability across multiple data engines and platforms, including Apache Doris, Apache Flink, Apache Spark, Dremio OSS, StarRocks, and Trino.
Jean-Baptiste Onofré, project management committee chair for Polaris, said the promotion reflects the project’s development and community support.
“This promotion to Top-Level Project status highlights the maturity of the Polaris community and its technology,” Onofré said.
The Apache Software Foundation said projects typically enter the organization through its Apache Incubator, where they are developed and guided before graduating to Top-Level Project status.
