Kafka is a distributed streaming platform that is used to build real-time data pipelines and streaming applications. It is designed to be fast, scalable, and durable.

You can use Kafka to deeply integrate into your existing data ecosystem. Goldsky supplies a message format that allows you to handle blockchain forks and reorganizations with your downstream data pipelines.

Kafka has a rich ecosystem of SDKs and connectors you can make use of to do advanced data processing.

Less Magic Here

The Kafka integration is less end to end - while Goldsky will handle a ton of the topic partitioning balancing and other details, using Kafka is a bit more involved compared to getting data directly mirrored into a database.
