Subject Re: cassandra in-production experiences with .7 series
Date Sun, 06 Mar 2011 03:20:41 GMT
Hi paul, 0.7 has had some problems but I think it's settling down. Hopefully some more people
with public facing sites can comment. 

WRT some of your other questions:
- I'm not aware of any specific performance issues with multi gets (multiget_slice) can you
be more specific. 
- You can implement paging through repeated calls to get_range_slice or get_slice, come higher
levels provide explicit support for this. AFAIK there are no plans to add SQL style LIMIT-OFFSET
support to the API.  see http://wiki.apache.org/cassandra/FAQ#range_rp
- I'm not aware of any specific 0.7 memory issues, if anything memory management under 0.7
is better. You will still need to size the JVM appropriately and configure things to match
your workload. Do you have any specific concerns. 

Hope that helps.
