Hi Guys!
I am not able to use timestamp micro columns save with HUDI.
I would like to save it keeping microsec granularity, but it only keeps milisec.
I have set this:
--conf spark.sql.parquet.outputTimestampType=TIMESTAMP_MICROS \
and also this in the hoodie:
"hoodie.parquet.outputtimestamptype": "TIMESTAMP_MICROS",
but when I read it back (with pyspark, load api), it's only millisecond
precision and unfortunately, I need the microsec in some case, because with
this I run into a Schrödinger's cat situation

So an entity has more than one states in the same time

someone enlighten me what should I do?
Before save everything is fine!
