Azure Cosmos DB Agent for Gluesync: Features & Compatibility

Index

Core principles

Gluesync’s Azure Cosmos DB agent depends on the Microsoft Azure Java SDK (azure-cosmos) to connect with the Azure Cosmos DB and interact through its SQL API.

Change data capture

This agent implements the Azure Cosmos DB Change feed processor which is part of the Azure V4 SDK to catch real-time data changes from Cosmos DB.

Security

The replication supports secure communication via TLS encryption when connecting to the Azure Cosmos DB.

Supported version

Works with Azure Cosmos DB DBaaS, any region.

Platform supported features

Feature Support Notes

Feature	Support	Notes
Target role	✅	Uses the Azure Cosmos Java SDK (SQL API) with TLS and auto-failover awareness.
Source role	✅	Consumes the Change Feed processor to capture inserts/updates/deletes in real time.
Snapshots	✅	Supports full snapshot tasks to seed Cosmos containers prior to CDC.
CDC	✅	Continuous replication based on the Cosmos Change Feed (V4 SDK).
CDC type	Change Feed processor	Built on Microsoft’s native Change Feed implementation.
Bulk load	N/A	Document writes stream via SDK batching; no staging-table bulk workflow.
Source persisted internal cache	N/A	State is maintained in Core Hub metadata; no disk cache required.
Target persisted internal cache	N/A	Writes are flushed directly to Cosmos DB via the SDK.
Driver / connector	Azure Cosmos Java SDK	Gluesync embeds the official `azure-cosmos` driver.
Chains	N/A	Not supported being it a NoSQL database.
Truncate operation support (reading)	N/A	Change Feed exposes record-level operations only; no TRUNCATE semantics.
Truncate operation support (writing)	N/A	The agent does not issue container-wide truncations automatically.
