Review Comment:
It's a prefix of the partition value, in this benchmark the created
partitions in mysql looks as follows:
```sql
mysql> select * from PARTITIONS limit 3;
+---------+-------------+------------------+-----------+--------+--------+----------+
| PART_ID | CREATE_TIME | LAST_ACCESS_TIME | PART_NAME | SD_ID | TBL_ID |
WRITE_ID |
