Review Comment:
   @XiangpengHao  I would appreciate your help with this change
   
   In https://github.com/apache/datafusion/pull/11862 you set this to 
`with_fixed_block_size`: 
   
https://github.com/apache/datafusion/pull/11862/files#diff-0007996e12eb1b2e63363974424f13330f85a7fc48e0c55381f8a30a0f372931R405
   
   However, since then you have added the dynamic growth size in 
https://github.com/apache/arrow-rs/pull/6136  which seems like it would be 
better
   
   Would it be possible for you to run your benchmarks again to make sure this 
doesn't cause regressions?
