Deltacad layers12/30/2023 ![]() For information on optimizations on Databricks, see Optimizations and performance recommendations on Databricks. Delta Lake operations are highly performant, supporting a variety of workloads ranging from large-scale ETL processing to ad-hoc, interactive queries. Many Databricks Runtime optimizations require Delta Lake. Upserts and deletes: Supports merge, update and delete operations to enable complex use cases like change-data-capture, slowly-changing-dimension (SCD) operations, streaming upserts, and so on. Time travel: Data versioning enables rollbacks, full historical audit trails, and reproducible machine learning experiments. Schema enforcement: Automatically handles schema variations to prevent insertion of bad records during ingestion. ![]() Streaming data ingest, batch historic backfill, interactive queries all just work out of the box. Streaming and batch unification: A table in Delta Lake is a batch table as well as a streaming source and sink. Scalable metadata handling: Leverages Spark distributed processing power to handle all the metadata for petabyte-scale tables with billions of files at ease. This guide provides an introductory overview, quickstarts, and guidance for using Delta Lake on Databricks.ĪCID transactions on Spark: Serializable isolation levels ensure that readers never see inconsistent data. Delta Lake on Databricks allows you to configure Delta Lake based on your workload patterns.ĭatabricks adds optimized layouts and indexes to Delta Lake for fast interactive queries. Delta Lake runs on top of your existing data lake and is fully compatible with Apache Spark APIs. Delta Lake provides ACID transactions, scalable metadata handling, and unifies streaming and batch data processing.
