Why replicate Azure Cosmos DB to Amazon Redshift?
Ready for analysis.

Centralizing your Azure Cosmos DB data in Amazon Redshift lets you join it with other data sources for cross-platform analytics and deeper insights.

Build reliable dashboards and reports by querying Azure Cosmos DB data directly in Amazon Redshift using SQL or your preferred BI tool.

Consolidate data from Azure Cosmos DB alongside other databases and applications in a single cloud data warehouse for a unified analytical layer.

  • Database replication for analytics

    Replicate your Azure Cosmos DB production data to Amazon Redshift without impacting database performance. Query historical data without load on your primary database.

  • Centralized data warehouse

    Bring Azure Cosmos DB data into Amazon Redshift alongside other sources to create a single source of truth for your organization.

  • Automated reporting

    Replace manual exports and spreadsheet-based reporting with automated pipelines from Azure Cosmos DB to Amazon Redshift. Connect BI tools like Looker, Metabase, or Power BI.

Data

What data can you replicate?
From Azure Cosmos DB to Amazon Redshift.

Weld syncs the objects the Azure Cosmos DB connector exposes into Amazon Redshift, and you choose which tables and fields to include. The connector's docs list what is available.

    Weld MCP server

    Ask your agent.
    It queries Amazon Redshift for you.

    Connect Claude, Cursor, ChatGPT or your own agent to Weld over MCP. It reads the Azure Cosmos DB context, finds the tables it needs and runs the query in Amazon Redshift.

    Under the hood

    Technical considerations.
    What to expect.

    Incremental syncing
    Weld uses incremental syncing where supported by the Azure Cosmos DB API, loading only new and updated records to minimize data transfer and warehouse costs.
    Change data capture
    For Azure Cosmos DB, Weld can use log-based replication (CDC) to capture inserts, updates, and deletes without querying the entire table on every sync.
    Schema handling
    Weld automatically manages schema changes. If Azure Cosmos DB adds new fields, they're detected and added to the corresponding Amazon Redshift tables.
    Data freshness
    Sync frequency depends on your Weld plan. Most connectors support schedules from every 5 minutes up to daily intervals.
    Security
    All data is encrypted in transit (TLS) and at rest. Weld is SOC 2 Type II compliant and supports IP whitelisting for database connections.
