[jira] [Created] (IMPALA-11993) [DOCS] Add an Iceberg section to TRUNCATE TABLE docs

Gabor Kaszab created IMPALA-11993:
-------------------------------------

             Summary: [DOCS] Add an Iceberg section to TRUNCATE TABLE docs
                 Key: IMPALA-11993
                 URL: https://issues.apache.org/jira/browse/IMPALA-11993
             Project: IMPALA
          Issue Type: Improvement
          Components: Docs
            Reporter: Gabor Kaszab


Currently our docs for TRUNCATE TABLE says that this drops all the data files for the tables. However, for Iceberg it's not the case as Iceberg 'only' creates a new snapshot for the table but don't delete the files, because for time travel they could be relevant for older snapshots.

An additional section in the docs would be nice to mention this.
