FilterExec: r_name = EUROPE → 1
row
HashJoinExec: mode=CollectLeft on (n_nationkey, s_nationkey) ←
nation BROADCAST

join_time=48ms]
DataSourceExec: nation (75 rows)
HashJoinExec: mode=Partitioned on (ps_suppkey, s_suppkey) ←
big⋈big HASH
[output_rows=839.8K, build_mem=76.25M, join_time=108ms]
ShuffleReaderExec: stage 5, coalesce: 3 of 16 ← COALESCE 16→3
