    <p>Two thoughts. </p> <p>1) No, <a href="http://docs.basho.com/riak/latest/tutorials/fast-track/Links-and-Link-Walking" rel="nofollow">Linking</a> (in the sense of Riak Link Walking) is very likely not the right way to implement this. For one, each link is stored as a separate HTTP header, and there is a recommended limit in the HTTP spec on how many header fields you should send. (Although, to be fair, in tests you can use upwards of a 1000 links in the header with Riak, seems to work fine. But not recommended). More importantly, querying those links via the Link Walking api actually uses MapReduce on the backend, and is fairly slow for the kind of usage you're intending it for.</p> <p>This is not to say that you can't store JSON objects that are lists of links, sure, that's a valid approach. I'm just recommending against using Riak links for this.</p> <p>2) As for how to properly implement it, that's a harder question, and depends on your traffic and use case. But your general approach is valid -- copy the feed for some X value of updates (whether X is 500 or much smaller should be determined in testing), and link when the number of updates is greater than X. </p> <p>How should you link? You have 3 choices, all with tradeoffs. 1) Use Secondary Indices (2i), 2) Use Search, or 3) Use links "manually", meaning, store JSON documents with URLs that you dereference manually (versus using link walking queries).</p> <p>I highly recommend watching this video: <a href="http://vimeo.com/album/2258285/page:2/sort:preset/format:thumbnail" rel="nofollow">http://vimeo.com/album/2258285/page:2/sort:preset/format:thumbnail</a> (Building a Social Application on Riak), by the Clipboard engineers, to see how they solved this problem. (They used Search for linking, basically).</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
