>
> Spark executes clustering job will read clustering plan which contains
> multiple groups. Each group process many base files or log files. When we
> config param `
> hoodie.clustering.plan.strategy.sort.columns`, we read those files through
> spark's parallelize method, every file read will generate one sub task. It's
> unreasonable.
