Sylvain Lebresne commented on CASSANDRA-781:
--------------------------------------------
I add the same problem, range_slice on 2 nodes was missing results.
I updated to trunk and applied 781.txt. It fixes the missing results but
introduce a timeout exception (I don't believe it is the patch fault though).
The timeout happens with consistencyLevel.ONE (but I suspect it could happen
with QUORUM too). Looking a bit to the details, it seems that
RangeSliceResponseResolver wait for a response from every live natural
endpoints (in isDataPresent()). But in StorageProxy, the rangeSlice message is
only sent to 'responseCount' endpoints (which will be 1 for
consistencyLevel.ONE). Hence the timeout.
I'm not sure what would be the best way to deal with that though.

> get_range_slice() does not return the same set of keys as get_key_range() in
> 0.5.0 final.
> I posted a program to reproduce the behavior:
> http://www.mail-archive.com/[email protected]/msg01474.html
> Apparently, you must have more than one node to get the behavior. Also, it
> may depend on the locations of the nodes on the ring.. I.e., if you don't
> generate enough keys randomly, then by chance they could all fall on the same
> host and you might not see the behavior, although I was able to get it to
> happen using only 2 nodes and 10 keys.
