Hi Shahid,

   its a well explained document, just need few clarifications,

a) once compaction is done the segments and its blocks will be invalidated,
LRU's scope is to evict the unused objects from memory or  least recently
used objects from memory, but after compaction the segment itself becomes
invalid,So is it really require to hold such objects in LRU cache and wait
for eviction  till its memory size gets full?

Thanks,
Sujith
