--------------------------------------
[~gszadovszky] I found that in some cases the performance will be worse:
|Case|Parquet 1.11 Vectorized(ms)|Parquet 1.11 Vectorized(Pushdown)(ms)|Parquet
1.10 Vectorized(ms)|Parquet 1.10 Vectorized(Pushdown)(ms)|%Improved|
|Select 1 distinct string row (value <=> '100')|6309|1418|7113|528|1.68560606|
