DistribuitionColumns, how does it work?


I am running the Dremio CE 4.1.4, and when I was querying for all reflections, I found a column named DistribuitionColumns, but I didn’t find anything on the docs. I am familiar with the concept of partitionColumn.

I found this using this query:

SELECT distributionColumns FROM sys.reflections

It returned NULL for all reflections.

Is this feature already on production? How does it work?

@balaji.ramaswamy Can you explain how does it work?


Currently we do not use the DISTRIBUTED BY clause
