Table Format

A layer that organizes files in a data lake into a structured table, enabling SQL-like features like ACID and time-travel.

Table formats like Iceberg, Hudi, and Delta Lake sit on top of Parquet files to provide metadata. This metadata allows query engines to know which files belong to a table, enabling ACID transactions and hidden partitioning.
