How do I replicate Dynamo DB data to ClickHouse?

Sign up for Weld, connect Dynamo DB as a source and ClickHouse as a destination. Weld handles the extraction, loading, and lets you transform data using SQL or dbt.

What Dynamo DB data can I replicate to ClickHouse?

You can replicate the objects the Dynamo DB connector exposes. The available objects depend on your Dynamo DB account permissions and configuration.

How often does Weld replicate data from Dynamo DB?

Sync frequency depends on your Weld plan. Schedules range from every 5 minutes to daily intervals. Each sync processes only new and changed data.

Can I transform Dynamo DB data before it lands in ClickHouse?

Yes. Weld supports SQL-based transformations in the platform and integrates with dbt Cloud. You can clean, join, and model your data before analysis.

Is the Dynamo DB to ClickHouse integration secure?

Yes. Weld encrypts all data in transit and at rest, is SOC 2 Type II certified, and supports IP whitelisting. Credentials are stored encrypted and never logged.

Under the hood

Technical considerations.
What to expect.

Incremental syncing: Weld uses incremental syncing where supported by the Dynamo DB API, loading only new and updated records to minimize data transfer and warehouse costs.
Change data capture: For Dynamo 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 Dynamo DB adds new fields, they're detected and added to the corresponding ClickHouse 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.
