My work for Cassandra 0.7 just started, which ensures existing API working for 0.7. Supporting new features, like creating KeySpace and ColumnFamily, will be added once the existing functionality tested. You may follow changes on http://code.google.com/p/jassandra/. Dop From: GH [mailto

Hi Dop, Do you have any code on dynamically creating KeySpace and ColumnFamily. Currently I was all but creating a new client to do that which seems to be the wrong way. If you have something that works that will put me on the right track I hope. Gavan On Mon, Jul 12, 2010 at 2:41 AM, Dop Sun

Re: Question about CL.ZERO

And, to be clear, there is no good reason to use CL.ZERO and it can be a serious resource hog on the coordinator. On Sun, Jul 11, 2010 at 9:21 AM, ChingShen wrote: > Hi all, > >   Does it mean that the coordinator node always return success to the client > at CL.ZERO? But if the coordinator node

That looks like it was asked to move when it didn't know about any other nodes in the cluster. Usually this indicates a misconfiguration. On Sun, Jul 11, 2010 at 7:07 AM, Sagar Agrawal wrote: > When I did nodetool move , nodetool streams for that node shows > mode:bootstrapping > but modetool m

Based on current source codes in the head, moving from 0.6.x to 0.7, means some code changes in the client side (other than server side changes, like storage_conf.xml). Something like: 1. New Clock class instead of timestamp: this may be trivia, but it takes some time to change 2.

Question about CL.ZERO

2010-07-11 Thread ChingShen
Hi all, Does it mean that the coordinator node always return success to the client at CL.ZERO? But if the coordinator node sends a request to a given node B(RF=1), then B is down, what happened? The coordinator node will write the hint locally? Thanks. Shen

advice, is cassandra suitable for a multi-tanency vBulletin type application?

2010-07-11 Thread S Ahmed
I want to build a vBulletin type application (forums, threads, posts, user management, etc). Support multi-tenancy for a Saas type environment. Would Cassandra be suitable for this type of application? Thanks in advance.

Re: Strange "Address already in use" error

2010-07-11 Thread Roger Schildmeijer
Something is already using the port (probably 7000 (default, used internal by cassandra)) you tried to bind. Use e.g. 'lsof -i' to investigate the port usage further. // Roger Schildmeijer On 11 jul 2010, at 17.15em, osishkin osishkin wrote: > I'm testing a simple Cassandra cluster on two mac

I want to move on to 0.7 using this API rather than storage-conf.xml conversion. Any info that you can advise on how you used it would be much appreciated. Thanks Gavan
