Delta Lake

Delta Lake is a versatile, open-source storage framework that transforms data lakes into reliable lakehouses with full transactional guarantees.

Key Features:

• ACID Transactions — Protect data integrity with serializable isolation across concurrent reads and writes.
• Time Travel — Access and revert to earlier data versions for audits, rollbacks, and reproducibility.
• Schema Evolution — Safely evolve table schemas without rewriting existing data.
• UniForm — Read Delta tables with Iceberg and Hudi clients for universal lakehouse interop.
• Unified Batch and Streaming — Ingest and query data with exactly-once semantics across both modes.
• Multi-Engine Support — Works with Spark, Flink, Trino, Snowflake, BigQuery, and more.

Whether you're building ETL pipelines, unifying batch and stream processing, or managing petabyte-scale lakes, Delta Lake provides production-ready lakehouse storage.
