> This occurs b/c SparkHoodieTableFileIndex produces incorrect partition schema
> at XXX
> where it properly handles only `TimestampBasedKeyGenerator`s but not the
> other key-generators that might be changing the data-type of the
> partition-value as compared to the source partition-column (in this case it
> has `ts` as a long in the source table schema, but it produces
> partition-value as string)
