Amazon S3

Amazon S3 is an object storage service that offers industry-leading scalability, data availability, security, and performance. Weld's Amazon S3 connector is a fully managed ELT integration that extracts raw data from Amazon S3, replicates and loads it into your centralized data warehouse. Once landed, the data is represented in a clean, navigable schema where analysts can easily access and query it alongside the rest of your organization's data using SQL or dbt.

FAQs

What is a connector?

A connector links Weld to apps, files, ad platforms, and databases to move data to and from them. Each connector supports as many syncs as you need.

What data sources can I connect to Weld?

Weld supports a wide range of data sources, including databases, cloud storage, and APIs. You can find the full list on the connectors page.

What if I can’t find the connector I need?

We are constantly building new integrations based on customer demand. You can also build a custom connector yourself using the Weld Connect API.

Is there a free trial available?

Yes, Weld offers a 14-day free trial with no upfront credit card requirement. This lets you explore all features before committing to a paid plan.

Does Weld need to connect directly to my production database?

No. With high throughput systems, we recommend creating a read replica to avoid unnecessary load on your production services.

Does Weld store my data?

Weld does not store your data. We are only responsible for moving data from source to destination, we simply help you transfer and prepare it for analysis.
