> The existing work for HDFS-9806 uses an implementation of the {{FileRegion}} read from a csv file. This is good for testability and diagnostic purposes, but it is not very efficient for larger systems.
> There should be a version that is similar to the {{TextFileRegionFormat}} that instead uses LevelDB.
