I could be wrong, but I believe there’s metadata overhead for each sibling, so even if all data in all siblings needs to be retained, it’s still more efficient to merge and save them as one object. -John On Dec 20, 2013, at 6:01 PM, Andrew Stone wrote: > Think of an object with thousands of s

Think of an object with thousands of siblings. That's an object that has 1 copy of the data for each sibling. That object could be on the order of 100s of megabytes. Everytime an object is read off disk and returned to the client 100mb is being transferred. Furthermore leveldb must rewrite the enti

I'd like to get started with Riak 2.0, and would appreciate insight/feedback on the following: 1. Since a client does not exist for 2.0, I was planning on using Jersey and Jackson to make http calls to the db. Has anyone tried this and if yes, how difficult was it? Are there any other cli

I feel the need to point out that with just a key or two you're probably only talking to 3/5 of the machines. for a single key adding extra nodes won't make it faster. (As I understand it) - Peace Dave On Fri, Dec 20, 2013 at 3:35 AM, Russell Brown wrote: > > On 20 Dec 2013, at 10:18, Georgio

Hi Georgio, With data that small I doubt there is a difference in perf. Can I get some more info, please? Are you getting 2400 reqs a second against a single key? What backend are you using? What is the spec of the machines? Are they real or on some cloud? Network? Is this perf figure agains

Hi Guys, I'm still evaluating riak & riak-cs. On my five node cluster, with riak only, I am only able to do 2400 requests per second. I have two keys, one a one byte key, and another a 4kb key, the performance doesn't change against either. Is this the best that I can expect to get from this, I
