Can you merge parquet partitions?

I know you can define tables as parquet format like PARTITION BY HOUR FORMAT PARQUET WAL;
Can you then merge the parquet files and they would still work?

Lets say from HOUR to DAY?

Hey Holger,

You can’t repartition on any table like that, native or parquet. But you can export a daily file from the table, or copy the data to another parquet table that is day partitioned.

A direct concatenation of the files won’t work.
