Review comment:
@wangxianghu Thank you for your review. My opinion is this：In
accordance with the habit of using Spark, the partition field value
corresponding to partitionBy is the original value, so the default is to use

type, the rules are not easy to determine. For example, if a field is long, we
Do you need to convert to TIMESTAMP? If you want to convert, but the value is
not a timestamp, an error will be reported, so SIMPLE is used by default. If
you want to use TIMESTAMP, users can directly use
```hoodie.datasource.write.partitionpath. field```Go to specify
