Dremio materialized tables

Hi guys, I need a help.

I have a project where I use dbt+dremio+nessie, the dbt-dremio version is 1.8.0 and Nessie is 0.91.3. All works fine, but when I create a materialized table, one new folder aways is created in my object storage. I don’t use incremental models in this tables. Why Dremio isn’t creating just one folder with the data? Following some images

@Ferrarini When you say “when I create a materialized table”, are you referring to Dremio reflections?

@balaji.ramaswamy no, is simple iceberg tables. I don’t have any reflection in my project.

@Ferrarini When you say “when I create a materialized table” do you mean that you create an iceberg table?

Yes, all tables are Iceberg tables and build with dbt.

@Ferrarini Thanks for the clarification

Can you please send 2 of your CTAS table script? Would to see why they are going as separate folders



@balaji.ramaswamy the problem was resolved when I did downgrade for Dremio OSS version 25.2 to Dremio version 25.0. I thing that bug just happens with dbt+dremio+Nessie in the version 25.2 from Dremio
