Antoine Pitrou commented on ARROW-7251:
---------------------------------------
The default is not None:
{code:python}
>>> from pyarrow import csv
>>>
>>>
>>> opts = csv.ReadOptions()
>>>
>>>
>>> opts.block_size
>>>
>>>
1048576
{code}
By changing this value you will control the size of chunks. But do note this
has an impact in performance, especially in parallel mode.
