stack commented on HBASE-14921:
-------------------------------
Diagrams are beautiful in the pdf....
High-level questions:
# Is MemstoreCompactingIterator what used to be a 'snapshot'? You interject
this Iteration step rather than move current MemStore to be a 'snapshot'?
# On your list of todos, #1 and #2 seem fine (I think [~anoop.hbase] and
[~ram_krish] are doing #2 for you).
# I'm interested in how #3 will be done (smile).
# What is this "...currently impossible to get the chunk ID out of already
created cell metadata"
All looks great. Let me see patch....
