Move your data from Azure Cosmos DB with your free account

The Azure Cosmos DB connector captures documents from your Cosmos DB collections into Estuary collections. It supports both real-time streaming via change streams and batch modes for collections that don’t support change streams.

• Supports multiple capture modes: Change Stream Incremental (real-time), Batch Snapshot, and Batch Incremental
• Automatically detects time series collections and uses optimal cursor fields for efficient polling
• Captures inserts, updates, and deletes when using change streams
• Batch modes enable flexible scheduled scans for collections without change stream support
• Works securely within Estuary’s Private and BYOC environments for compliance and governance

💡 Tip: For best performance, ensure your cursor field (such as _id or timeField) is indexed to optimize incremental captures.
