So no matter how small the bucket it will traverse the whole key space for a map reduce. We sat down and did some thinking of how to work our data differently as we have a similar use case to you and decided on nested docs using Ripple. In our case we had special buckets for each user like you describe below. Now that bucket is a nested JSON struct inside the user object instead of a separate bucket. In your use case you could have all statuses as a nested struct on your user object and display would be a matter of linkwalking all an user's friends and parsing status content with some time/sorting.

We have entities users, friends, statuses and comments in a web app 2. Users can make friends with other users 3. Users can post statuses 4. Friends ( Users ) can comment on user's statuses At first i thought on having a bucket called "users" with all users and then for friend linkage i was thinking on having personal buckets like "rohman_friends", "fyodor_friends", etc... with the keys to the users instead of a big "friends" bucket for easy querying... but seems i'm wrong... so... How would you distribute the data on buckets? and how would you run MapReduce jobs? Would you use a support SQL database to store relationship between keys? is possible on an only Riak environment? thanks Rohman line logo *Antonio Rohman Fernandez* CEO, Founder & Lead Engineer roh...@mahalostudio.com [3] roh...@mahalostudio.com> *Projects* MaruBatsu.es PupCloud.com Wedding Album line _______________________________________________ riak-users mailing list riak-users@lists.basho.com [7] riak-users@lists.basho.com> http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com [8] >> -- line logo *Antonio Rohman Fernandez* CEO, Founder & Lead Engineer roh...@mahalostudio.com [10] roh...@mahalostudio.com> *Projects* MaruBatsu.es PupCloud.com Wedding Album line _______________________________________________ riak-users mailing list riak-users@lists.basho.com [14] http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com [15] -- [16] ANTONIO ROHMAN FERNANDEZ CEO, Founder & Lead Engineer roh...@mahalostudio.com [17] PROJECTS MaruBatsu.es [18] PupCloud.com [19] Wedding Album [20] Links: ------ [1] mailto:roh...@mahalostudio.com [2] http://mahalostudio.com [3] mailto:roh...@mahalostudio.com [4] http://marubatsu.es [5] http://pupcloud.com [6] http://wedding.mahalostudio.com [7] mailto:riak-users@lists.basho.com [8] http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com [9] http://mahalostudio.com [10] mailto:roh...@mahalostudio.com [11] http://marubatsu.es [12] http://pupcloud.com [13] http://wedding.mahalostudio.com [14] mailto:riak-users@lists.basho.com [15] http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com [16] http://mahalostudio.com [17] mailto:roh...@mahalostudio.com [18] http://marubatsu.es [19] http://pupcloud.com [20] http://wedding.mahalostudio.com
