Iceberg parallel partitioned inserts?

[nfoerster]

I have a question regarding the possibilities of parallel iceberg inserts when the data is partitioned. I tried it and had a lot of concurrency errors, I think because of problems during metadata write operation in the Iceberg itself. I'm just thinking if there is a setting or parameter to enable this feature.

insert into iceberg.test.table_test
     select * from iceberg.test.view_test where msgid={msgid}

Does using set session preferred_write_partitioning_min_number_of_partitions=1; help here ?
