Have you heard of a Delta Lake? What is up with that? In this third video in our new series on Delta Lake, Austin goes through the process of modifying the delta table created in the previous video, using different CRUD (Create, Read, Update, Delete) operations to modify the delta table, and showing of the ability to time travel with version history of the delta table stored in the transaction log.
Azure Synapse – Modifying Delta Tables is a feature of Azure Synapse that allows users to modify Delta tables. Delta tables are a new type of table available in Azure Synapse, which stores data in an immutable, append-only format and provides a unified programming model for both stream and batch data processing. With the ability to modify Delta tables, users can now update, delete, and insert data into existing Delta tables. This feature also enables users to dynamically control data retention, as well as add and remove columns and partitions. In addition, users can access Delta table data in real-time and take advantage of the flexible query and storage options provided by Azure Synapse.
