   My bad. It seems that I made a regression at `Taxi` data compression.
   
   **ORC 1.9**
   ```
   data/generated//taxi:
   total 2196176
   drwxr-xr-x  5 dongjoon  staff   160B Jan 17 08:02 .
   drwxr-xr-x  5 dongjoon  staff   160B Jan 17 08:07 ..
   -rw-r--r--  1 dongjoon  staff   299M Jan 17 08:03 orc.zstd
   ```
   
   **ORC 2.0**
   ```
   -rw-r--r--  1 dongjoon  staff   334M Jan 17 07:56 orc.zstd (level 1)
   -rw-r--r--  1 dongjoon  staff   299M Jan 17 08:16 orc.zstd (level 3)
   -rw-r--r--  1 dongjoon  staff   302M Jan 17 08:21 orc.zstd (level 4)
   -rw-r--r--  1 dongjoon  staff   300M Jan 17 08:27 orc.zstd (level 5)
   ```
   
   ZStd compression level looks inconsistent with this dataset and let me 
change the `zstd level` change back to 3 like the original proposal.
