You want Kafka talking to Flink, Spark writing to Iceberg, Trino querying the result, and maybe a catalog and a lineage tool watching over all of it. What you actually get is an afternoon lost to dependency conflicts, port clashes, and a Docker Compose file that grows a new bug every time you touch it.

I built odctl to make that afternoon disappear. It is a curated collection of open-source data technologies wrapped in a small CLI, and it is now available on PyPI.
