Review Comment:
Hey @Zouxxyy, Thanks for raising this issue!
The reason to collect the data here is that `HoodieData<WriteStatus>` will
be used multiple times after `performClustering`, I recall there is an
`isEmpty` check could take lots of time, so here we directly convert to a list
of WriteStatus, which will reduce the time.
For the second issue, I noticed this and raised a pr to fix it: #7343, will
that address your problem? Feel free to review it!
I think `performClusteringWithRecordsRDD` also has the same issue such as
using `RDDSpatialCurveSortPartitioner` to optimize data layout, it will call
`RDD.isEmpty`, which will raise a new job.
