Hi, I am running a simple query which performs JOIN operation between two parquet files and it takes around 3-4 secs and I noticed that 70% of the time is used by UNORDERED_RECEIVER.
Sample query is - select sum(sales),week from dfs.`C:\parquet-location\F8894180-AFFB-4803-B8CF-CCF883AA5AAF-Search_Snapshot_Data.parquet` where model_component_id in( select model_component_id from dfs.`C:\parquet-location\poc48k.parquet`) group by week Can we somehow reduce unordered receiver time?
