Apache XTable

What is Apache XTable?

Apache XTable, previously known as OneTable, serves as a translation layer for data lakehouse formats. Apache XTable allows seamless metadata translation between formats like Apache Hudi, Delta Lake, and Apache Iceberg. Apache XTable ensures that data can be written once and queried across different systems. This functionality promotes universal data accessibility and interoperability.

The development of Apache XTable began with the goal of solving interoperability issues in data lakehouses. Initially named OneTable, the project aimed to provide a neutral space for collaboration among various table formats. Apache XTable transitioned to an open-source project under the Apache Software Foundation. The community's support has driven continuous improvements and expanded capabilities.
