Jonathan Vexler commented on HUDI-8382:
---------------------------------------
With the fg reader implementation, we always use hadoopfs relation for every
query type. And I think we will be getting rid of the relation based
implementations in the near future so this pr is probably not necessary
> Improve MOR-Snapshot-Query performance for COW like table

> In some cases, a MOR table's latest (or view at time-travel specified
> instant) file-slices all have only base-file but empty log-files. When
> performs Snapshot-Query for these tables, we can regard it as
> MOR-ReadOptimized-Query and provide a HadoopFsRelation to Spark.
