Description

Is there any functionality in pyarrow that allows reading the file partially. Means if I wish to read only the first 10 rows from the parquet file. 

I got this situation while doing this:

`df = pd.read_parquet(path= 'filepath', nrows = 10)`  #Gave me error

I wanted to read just the 10 rows into pandas dataframe using the read_parquet, (read_parquet uses pyarrow as one of the engines to read parquet file). As the parquet file is considerably huge in size, if one wants to read only a few n rows is there any functionality we can add in the engine to do so?
