Iceberg tables : INSERT OVERWRITE support

Hi all !

In v4.9.1, setting the dremio.iceberg.enabled support key - that I found in the source code, I managed to INSERT INTO hdfs iceberg tables : it’s an incredible step toward a data lakehouse solution, a data vault - insert only - warehouse ! Thank you so much !

So, icing on the cake, when will it be possible to INSERT OVERWRITE ?

@tshiran, it seems that iceberg tables are enabled even on NAS sources.

I will adapt the dbt adapter for dremio, mainly the incremental materialization, and users may now be able to audit transformations’ duration.

Best regards from French west coast,


Hi @fetanchaud

We have not yet released support for iceberg yet. Yes, parameter is there but will be announcing GA in coming versions soon, thanks for the feedback


Sorry @balaji.ramaswamy, as I saw this in the sources, I thought I had missed the point, and that the feature was already in use. I will wait for official communication. Best.

Hello @balaji.ramaswamy , in our last exchange five months ago, iceberg support was to be announced soon. Could you please tell us if something is on the way ?
I would like to include iceberg tables in dbt-dremio adapter’s next release.

Best regards,


It is certainly slated to come by end of Q2 this year. It will be first released for Hive and then file system based sources


Hi @balaji.ramaswamy , in version 19 community edition, I cannot use CREATE TABLE my_table(my_column my_type…) command anymore, even with iceberg support enabled. Why such a regression ?

@fetanchaud, This is not an officially supported / released feature. Users can use support key dremio.iceberg.ctas.enabled to work with feature under development.
