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 SIMPLE. If we automatically infer whether to use TIMESTAMP based on the field 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 yes, I get your point. we'd better support both `SIMPLE` and `TIMESTAMP` type patitionpath in a unified way ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
