# Table Formats

e6data supports table formats that define how data is stored, managed, and queried in a data lake or lakehouse environment. These are the table formats we support, and each table format provides a specific set of features based on its design and capabilities.

These formats offer advanced functionalities such as ACID transactions, schema and partition evolution, time travel, and efficient metadata handling.

| [**Delta Lake**](/product-documentation/table-formats/delta-lake.md)         | Open-source storage layer that brings ACID transactions and scalable metadata handling to data lakes. Ideal for use cases requiring data reliability and consistency. |
| [**Apache Iceberg**](/product-documentation/table-formats/apache-iceberg.md) | High-performance table format built for analytic datasets. Supports schema evolution, partitioning, and time travel without sacrificing performance.                  |
| [**Apache Hudi** ](/product-documentation/table-formats/apache-hudi.md)      | Open-source storage format enabling efficient upserts, incremental processing, and time travel on data lakes.                                                         |
