Azure Cosmos DB analytical store now supports Change Data Capture (CDC), allowing customers to efficiently consume, at no RUs cost, a continuous and incremental feed of changes (inserts, updates, and deletes) from analytical store, add transformations like data flattening, and write the data to diverse targets, including but not limited to Delta Lake, Azure SQL Database, Azure Synapse Dedicated Pools, and Azure Data Explorer.
