String

Mongo prefers strings as data ype, so we change our id from Long to String.

LocalDateTime

Mongodb removed the nanosecond information from Date type and has a precision of milliseconds.

We can truncate LocalDateTime in Java:

Clock millisecondClock = Clock.tick(Clock.systemDefaultZone(), Duration.ofNanos(1000000)); 
LocalDateTime d = LocalDateTime.now(millisecondClock);
