72 records were distributed in 36 slices in chronological order, and the verification was completed.

Note: the day configured in rule.xml is divided into 24 parts, one is one hour, and we have a total of 36 shards, so the data inserted can only be limited to 36 hours at the beginning of each month, such as 2018100100-2018100211.
