FileDataIndexRegionHelper
FileDataIndexRegionHelper is responsible for writing a FileDataIndexRegionHelper.Region to the file or
reading a FileDataIndexRegionHelper.Region from file. |
| FileDataIndexRegionHelper.Region
A
FileDataIndexRegionHelper.Region Represents a series of buffers that are:
From the same subpartition
Logically (i.e. buffer index) consecutive
Physically (i.e. offset in the file) consecutive
The following example illustrates some physically continuous buffers in a file and regions
upon them, where `x-y` denotes buffer from subpartition x with buffer index y, and `()`
denotes a region. |
