Comment(by tomeu):

 Walter, Ben,

 the list view in the journal only asks the DS for the columns it needs to
 display. That _doesn't_ include the preview.

 So, we only send across the wire something like 100-200 bytes per entry.

 The preview and the rest of the metadata is retrieved from the datastore
 when the user clicks on the entry and goes to the detailed view.

 Ben, can you explain how you see this can affect performance?

 Ben, previews are so big because we cannot put binary data in the
 datastore: #2782. When we get this fixed, we'll save quite a bit of space
 on disk. And I'm pretty sure this will also improve performance.
