Partial Search Cookbook
Partial Search
is a search API available on Chef Server. (see Notes below for version compatibility)
It 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.
Since Chef Client 11.10.0 the partial_search capability has been built-in
so it does not require this cookbook.
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

provided by this cookbook. Please send comments to the chef-dev
mailing list.The partial search API is available in the Open Source Chef Server since 11.0.4
The partial search API is available in Enterprise Chef Server since 1.2.2
