Does it solve both problems in #16739? |
|
Not yet, still debugging, I think it is very close. |

- Both
LocalDateTimeandOffsetDateTimehave a methodwithNanowhich floor to whole seconds. Shorter than current implementation. - It seems
TIMESTAMPTZbranch getsOffsetDateTimeout but putsLocalDateTime. Is it intended or accidental? - Could you elaborate why it is necessary to remove the subsecond part? Maybe it only works when the MySQL table is declared with
DATETIMEandTIMESTAMP, but would fail withDATETIME(6)orTIMESTAMP(6). Specially, PostgreSQL (and RisingWave) default precision is 6 (i.e.timestamptzis short fortimestamptz(6)) while MySQL default precision is 0 (i.e.datetimeis short fordatetime(0)).- This may imply that we need to convert from 6 to whatever precision defined in downstream MySQL. (demo) Are we able to get that info from the downstream column?

It seems TIMESTAMPTZ branch gets OffsetDateTime out but puts LocalDateTime. Is it intended or accidental?
Intended. since downstream timestamp doesn't store timezone, so I convert to LocalDateTime
