-----------------------------------
hi [~harbby] After tracking, two problems were found:
1.Proctime and rowtime can't be used together in a table, you can only use
either.
2. The type returned by rowtime and proctime is timestamp, and you need to
specify this type.
I updated the update in detail at [https://github.com/harbby/sylph/issues/23]
> Adding time multiple times causes Runtime : java.sql.Timestamp cannot be cast
> to java.lang.Long
