    Datahike

    Datahike

    A durable Datalog implementation adaptable for distribution

    Datahike is a durable Datalog database powered by an efficient Datalog query engine. This project started as a port of DataScript to the hitchhiker-tree. All DataScript tests are passing, but we are still working on the internals. Having said this we consider Datahike usable for medium sized projects, since DataScript is very mature and deployed in many applications and the hitchhiker-tree implementation is heavily tested through generative testing.

    Apache Polaris

    Apache Polaris

    Apache Polaris, the interoperable, open source catalog

    ...By implementing the Iceberg REST catalog API, Polaris enables distributed data platforms to access shared table metadata without tightly coupling storage systems and query engines. This design allows organizations to run queries on the same Iceberg tables using tools such as Apache Spark, Flink, Trino, and other analytics engines while maintaining consistency across platforms. Polaris also focuses on data governance, security, and interoperability within large-scale cloud data architectures. Because Iceberg tables often exist across many services in a distributed ecosystem, the catalog helps coordinate metadata, schemas, and access policies in a unified system.
