mergeAdjacentDiskRanges

public static List<DiskRange> mergeAdjacentDiskRanges(Collection<DiskRange> diskRanges,
 io.airlift.units.DataSize maxMergeDistance,
 io.airlift.units.DataSize maxReadSize)

public static io.airlift.slice.Slice getDiskRangeSlice(DiskRange diskRange,
 Map<DiskRange,io.airlift.slice.Slice> buffers)

Get a slice for the disk range from the provided buffers. The buffers ranges do not have to exactly match diskRange, but diskRange must be completely contained within one of the buffer ranges.
