Review comment:
```suggestion
<td>The formatter that formats the partition timestamp string value
to timestamp, the partition timestamp string value is expressed by
'partition.time-extractor.timestamp-pattern'. For example, the partition
timestamp is extracted from multiple partition fields, say 'year', 'month' and
'day', you can configure 'partition.time-extractor.timestamp-pattern' to
'$year$month$day', and configure `partition.time-extractor.timestamp-formatter`
to 'yyyyMMdd'. By default the formatter is 'yyyy-MM-dd HH:mm:ss'.
