Vijay updated CASSANDRA-2392:
-----------------------------
Attachment: 0001-CASSANDRA-2392-v6.patch
The problem with v5 is that when we do the loadSummary() we will have ibuilder
and dbuilder populated... when boolean readIndex is true we will repopulate it
again....
Attached v6 fixes it and tested. Thanks!

> For nodes with millions of keys, doing rolling restarts that take over 10
> minutes per node can be painful if you have 100 node cluster. All of our time
> is spent on doing index summary computations on startup. It would be great if
> we could save those to disk as well. Our indexes are quite large.
