Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place.

Partial Search Cookbook

Partial Search is a new search API currently available only on Opscode Hosted Chef that can be used to reduce the network bandwidth and the memory used by chef-client to process search results.

This cookbook provides an experimental interface to the partial search API by providing a partial_search method that can be used instead of the search method in your recipes.

The partial_search method allows you to retrieve just the attributes of interest. For example, you can execute a search to return just the name and IP addresses of the nodes in your infrastructure rather than receiving an array of complete node objects and post-processing them.

Install

Upload this cookbook and include it in the dependencies of any cookbook where you would like to use partial_search.

Usage

When you call partial_search, you need to specify the key paths of the attributes you want returned. Key paths are specified as an array of strings. Each key path is mapped to a short name of your choosing. Consider the following example:

partial_search(:node, 'role:web',
   :keys => { 'name' => [ 'name' ],
              'ip'   => [ 'ipaddress' ],
              'kernel_version' => [ 'kernel', 'version' ]
            }
).each do |result|
  puts result['name']
  puts result['ip']
  puts result['kernel_version']
end

In the example above, two attributes will be extracted (on the server) from the nodes that match the search query. The result will be a simple hash with keys 'name' and 'ip'.

Notes

  • We would like your feedback on this feature and the interface provided by this cookbook. Please send comments to the chef-dev mailing list.

  • The partial search API will eventually be available in the Open Source Chef Server.

  • The partial search API is available in Opscode Private Chef since 1.2.2
