Subject Could anybody help to explain why there is such a big gap in 'ProbeTime' and How to fix this gap?

Hi everybody,


Recently I ran a simple PHJ on‘parquet’ and ‘kudu’with this sql

select count(*) from lineitem as l, orders as o where l.l_orderkey =
o.o_orderkey and o.o_orderdate < '1996-01-01' and o.o_orderdate >=


And I found that the ‘ProbeTime’ on ‘kudu’is much larger than on


Below are the plans and profiles:


Thanks in advance.
