Apache XTable (incubating) is a cross-table converter that translates lakehouse table format metadata between Apache Hudi, Apache Iceberg, and Delta Lake, enabling omni-directional interoperability across data processing systems and query engines. It is not a new table format; it reads existing table metadata and writes equivalent metadata for other formats so the same data files can be read by different engines.

Use cases

• convert delta lake tables to apache iceberg
• make hudi tables queryable by snowflake or databricks photon
• avoid vendor lock-in to a single lakehouse table format
• sync table metadata between hudi iceberg and delta
• let multiple query engines read the same data lake table
• migrate from onetable to apache xtable

When to choose

• you need existing data files readable as multiple table formats without rewriting data
• you want a vendor-neutral, community-driven alternative to Delta Lake Uniform
• you need omni-directional conversion among Hudi, Iceberg, and Delta rather than one-way sync
• you plan to extend support to other formats like Apache Paimon via simple interfaces

When to avoid

• you only use a single table format and never need cross-format access
• you need a new storage format rather than metadata translation
• you require a fully graduated, non-incubating Apache project
• your pipeline depends on format-specific features that do not translate across metadata layers
