----------------------------

[~garyli1019] I think we could update the DOC after cutting the 0.5.1 docs and merge it to
0.5.2 docs, FYI: [~bhasudha]

> For the use case that I only need to pull the incremental part of certain partitions,
I need to do the incremental pulling from the entire dataset first then filtering in Spark.
> If we can use the folder partitions directly as part of the input path, it could run
faster by only load relevant parquet files.
> Example:
>  
> {code:java}
> spark.read.format("org.apache.hudi")
> .option(DataSourceReadOptions.VIEW_TYPE_OPT_KEY,DataSourceReadOptions.VIEW_TYPE_INCREMENTAL_OPT_VAL)
> .option(DataSourceReadOptions.BEGIN_INSTANTTIME_OPT_KEY, "000")
> .load(path, "year=2020/*/*/*")
>  
> {code}
