Hi, Are there recommendations for or work on using non-microsecond timestamps with Iceberg? For our use case, we'd want to read, write, and partition with non-microsecond timestamps (specifically, millisecond and nanosecond).
For milliseconds, we could convert to and from microseconds outside of Iceberg although this is not ideal. But this doesn't work for nanoseconds without losing precision. In a similar issue<https://github.com/trinodb/trino/issues/1284>, there were suggestions for Iceberg to support custom transforms for timestamps. Is that in the plan? Thanks, Tina
