Currently there is a hard dependency to Postgres for the bookkeeping tables of mara. I'm working on dockerizing the example project to make the setup easier.

For ETL, Mysql, Postgres & SQL Server are supported (and it's easy to add more).

I'm a bit confused about this. What if the target is HDFS? Why this dependency on SQL databases for ETL?
