> 1. create a table and insert some data:
> {code}
> create table ice_t (i int, p int) partitioned by spec (truncate(10, i)) stored by iceberg;
> insert into ice_t values (1, 1), (2, 2);
> insert into ice_t values (10, 10), (20, 20);
> insert into ice_t values (40, 40), (30, 30);
> {code}
> Then concurrently execute the following jobs:
> Job 1:
> {code}
> insert into ice_void select i*100, p*100 from ice_void;
> {code}
> Job 2:
> {code}
> insert overwrite ice_void select i+1, p+1 from ice_void;
> {code}
> If Job 1 finishes first, Job 2 still succeeds for me, and after that the table content will be the following:
> {code}
> 2      2
> 3      3
> 11     11
