> Insert overwrite should be disabled where the target Iceberg table is a
> bucket partitioned table, since which existing partitions will be overwritten
> is very hard to predict from a user's POV, as it depends on the bucket hash
> values calculated for the new dataset's rows. It's better to be on the safe
> side and disable this operation to avoid unwanted data loss.
> Note: this the same approach followed by Impala too.
