Azure Cosmos DB connector details
The Azure Cosmos DB connector captures documents from your Cosmos DB collections into Flow 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.

Tinybird connector details
Real-time analytics in Tinybird start with live data — and Estuary makes that possible. By using the Tinybird variant of the Dekaf connector, you can stream data from Flow collections directly into Tinybird as Kafka-compatible messages. This gives you a continuous, low-latency data feed for powering dashboards, APIs, and user-facing analytics.
- Instant data delivery: Flow publishes updates and inserts in real time to Tinybird via Avro-encoded Kafka topics
- Effortless authentication: Connect using your Flow materialization name as the username and your auth token as the password
- Flexible workspace setup: Works seamlessly with both Tinybird Forward (CLI-based) and Tinybird Classic (UI-based) environments
- Schema-aware integration: Includes an Avro schema registry endpoint that Tinybird can automatically decode
- Custom deletion handling: Choose between kafka (null-value deletes) or cdc (explicit deletion records) modes for soft or hard delete logic
- Optimized for analytics: Configure Tinybird datasources using MergeTree or ReplacingMergeTree engines for deduplication and efficient querying
💡 Tip: When using CDC deletion mode, extract the _is_deleted field and apply the FINAL keyword in Tinybird queries to automatically filter out deleted rows.
