Choosing well
Match the processing model
Look at how each service accepts and handles incoming data, and choose a processing approach that suits your pipeline. Exactly-once processing is a listed comparison point, so review it alongside your reliability needs.
Choose a deployment style
Deployment options in this category include managed web services and self-hosted software. Using a web service may limit setup, whereas self-hosting lets you decide where the system operates.
Check connectors and languages
Source connectors determine which data systems can feed a pipeline. Supported languages affect how you build and maintain jobs, so check both before choosing a product.
