    Resolution: Won't Fix

Sorry if this spam's things, however it's unlikely that I'll work on these.

>    Affects Versions: 2.4.1

>            Priority: Minor
>             Fix For: 4.0

> When LUCENE-1313 is completed, it would be good to have a way to
> replicate segments from one IndexWriter to another.
> * Callback on successful flush (maybe for other events as well?)
> * Ability to access files for a segment (which would presumably
> be read from the IW ramdir), then copy them to a temporary
> serialized ramdir (or equivalent as ramdir uses extra space in
> blocks, whereas we'll already know the size of the files before
> we write them).
> * On the receiving end, we may be able to use
> addIndexesNoOptimize(Directory[]), however this would entail
> each directory having an extraneous segment_N file for each
> replicated update (so we may want another format). 
> * It will rely on having a new public version of SegmentInfo.
