What is a .delta file?
File Extension Details
The .delta file extension is primarily associated with Delta Lake, an open-source storage layer that brings reliability to data lakes. Delta Lake provides ACID transactions, scalable metadata handling, and unifies streaming and batch data processing. The .delta files are JSON-formatted transaction log files that record every change made to a Delta table. When data is inserted, updated, or deleted, Delta Lake records these operations as an ordered sequence of actions in these log files. This architecture allows for 'time travel' or data versioning, enabling users to query previous snapshots of the data. Because these files are immutable and stored in the transaction log directory (_delta_log), they serve as the single source of truth for the state of the data, ensuring that concurrent reads and writes do not corrupt the underlying Parquet data files. They are essential for maintaining data integrity in large-scale big data environments.
