The difference is:

 Avg_row_length	Data_length
 
-15	30
 
+18	36

Comment by Sergei Petrunia [ 2018-05-23 ]

These numbers may vary (I assume depending on the data layout in RocksDB).

The test actually has replace_column for each SHOW TABLE STATUS . this one doesn't have it because of an obvious typo.
