Hi team, I have few questions: I need to check on few things : 1. Why we are using MySQL database instead of Postgres sql 2. And what's the difference in bitnami MySQL or datahub MySQL and bitnami Kafka or bitnami Kafka 3. Why we are using Kafka bitnami in datahub prerequisites and datahub -Kafka in datahub ?

Hey, 1. Postgres is also an option to use Datahub but we don’t have experience with that. I know there are some people in the community who uses Postgres. 2. Bitnami is just a provider who creates docker images. The image itself doesn’t really matter until it is a mysql. It can be docker image, or even you can connect with cloud mysql like rds on AWS, cloud sql on GCP, etc… 3. Same here like the 2nd one. The image itself doesn’t matter until it is Kafka.

But when I tried to deploy datahub prerequisites with the datahub MySQL image that I have pulled and used in datahub, it did not work

Where it did not work? And what error you got?

The bitnami MySQL container image may have different customisations and config compared to the default MySQL image that the datahub compose file uses.
