Engineering Lakehouses with Open Table Formats
By :
Delta Lake’s transaction log protocol is a rigorously designed specification that enforces ACID compliance and ensures consistent transactions for data stored in distributed filesystems or object stores. The protocol bridges the limitations of eventual consistency in object stores (such as S3) by providing strong transactional guarantees required for reliable operations. By using the transaction log with the protocol, Delta Lake provides a unified framework for reads, writes, and concurrent operations, enabling us to build reliable lakehouse architectures.
The transaction log protocol is built around the concept of serializable transactions, where every modification to a Delta table results in a new, atomic version of the table. Each version is defined by a contiguous, monotonically increasing integer, and the transaction log serves as the single source of truth, maintaining a complete record of all changes.
