Engineering Lakehouses with Open Table Formats
By :
In this section, we will go over some of the unique capabilities and components that set Delta Lake apart.
CDF in Delta Lake is designed to track and surface row-level changes (inserts, updates, or deletes) across versions of a table. It is particularly beneficial for incremental processing workloads, where minimizing the volume of data processed directly translates to reduced latency and cost. By categorizing changes as insert, update_preimage, update_postimage, and delete, Delta Lake provides granular visibility into how data evolves over time. This makes it an ideal solution for scenarios requiring data replication, debugging, or compliance audits. Unlike traditional CDC systems that rely on external tools or databases, Delta Lake achieves this functionality natively through its transaction log.
CDF’s integration with Delta Lake’s transaction protocol enables efficient tracking of changes. The transaction...
