All - I just started working with Riak, and am using the riak-client Ruby gem.
When I delete a key from a bucket, and try to fetch the value associated with that key, I get a 404 error (which is reasonable). However, it remains in the bucket's list of keys (i.e. the value returned by bucket.keys(). Why is the key still reported to exist in the bucket? Is bucket.keys cached, and therefore unaware of the deletion? Here's a riak-client Ruby script and its output in irb that illustrates this: ree-1.8.7-2010.02 :001 > require 'riak' => true ree-1.8.7-2010.02 :002 > ree-1.8.7-2010.02 :003 > client = Riak::Client.new => #<Riak::Client http://127.0.0.1:8098> ree-1.8.7-2010.02 :004 > bucket = client['links'] => #<Riak::Bucket {links}> ree-1.8.7-2010.02 :005 > key = bucket.keys.first => "4000-17.xml" ree-1.8.7-2010.02 :006 > object = bucket[key] => #<Riak::RObject {links,4000-17.xml} [text/xml]:(6430 bytes)> ree-1.8.7-2010.02 :007 > object.delete => #<Riak::RObject {links,4000-17.xml} [text/xml]:(6430 bytes)> ree-1.8.7-2010.02 :008 > bucket.keys.first => "4000-17.xml" ree-1.8.7-2010.02 :009 > object = bucket[key] Riak::HTTPFailedRequest: Expected [200, 300] from Riak but received 404. not found from /Users/kbennett/.rvm/gems/ree-1.8.7-2010.02/gems/riak-client-0.9.4/lib/riak/client/net_http_backend.rb:55:in `perform' from /Users/kbennett/.rvm/rubies/ree-1.8.7-2010.02/lib/ruby/1.8/net/http.rb:1054:in `request' from /Users/kbennett/.rvm/rubies/ree-1.8.7-2010.02/lib/ruby/1.8/net/http.rb:2142:in `reading_body' from /Users/kbennett/.rvm/rubies/ree-1.8.7-2010.02/lib/ruby/1.8/net/http.rb:1053:in `request' from /Users/kbennett/.rvm/rubies/ree-1.8.7-2010.02/lib/ruby/1.8/net/http.rb:1037:in `request' from /Users/kbennett/.rvm/rubies/ree-1.8.7-2010.02/lib/ruby/1.8/net/http.rb:543:in `start' from /Users/kbennett/.rvm/rubies/ree-1.8.7-2010.02/lib/ruby/1.8/net/http.rb:1035:in `request' from /Users/kbennett/.rvm/gems/ree-1.8.7-2010.02/gems/riak-client-0.9.4/lib/riak/client/net_http_backend.rb:47:in `perform' from /Users/kbennett/.rvm/gems/ree-1.8.7-2010.02/gems/riak-client-0.9.4/lib/riak/client/net_http_backend.rb:46:in `tap' from /Users/kbennett/.rvm/gems/ree-1.8.7-2010.02/gems/riak-client-0.9.4/lib/riak/client/net_http_backend.rb:46:in `perform' from /Users/kbennett/.rvm/gems/ree-1.8.7-2010.02/gems/riak-client-0.9.4/lib/riak/client/http_backend/transport_methods.rb:59:in `get' from /Users/kbennett/.rvm/gems/ree-1.8.7-2010.02/gems/riak-client-0.9.4/lib/riak/client/http_backend.rb:72:in `fetch_object' from /Users/kbennett/.rvm/gems/ree-1.8.7-2010.02/gems/riak-client-0.9.4/lib/riak/bucket.rb:101:in `[]' from riak-delete-failure.rb:9 Thanks, Keith _______________________________________________ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
