file access logic
When data has to be read from file (immutable sstable), where in the
codebase/logic does it go about searching for the location of the key?
Once it has found the key, is the exact location in terms of its location on
disk stored in a index for future lookups?
When data is stored on disk, is it just a serialized version of the CF
object? And then it streams this data to the calling client?
