Aiven for Apache Kafka vs MongoDB: Which is best for you?

The built in log feature is very basic, although it can integrate with more complete products.

We are just starting to use the product, but we've run into one minor bug, and I have some concerns on performance so far - but performance issues are probably not caused be Aiven, but rather Kafka client lib/configuration.

Costs on MongoDB can also grow faster than expected as data and traffic scale.

It doesn't compel you to follow specific schema, neither is it causing complexity on you
