This cookbook is deprecated in favor of partial_search introduced in chef 11 API
LightWeight search is a wrapper library around Chef's built-in search which casts node objects to memory efficient "Lightweight Node" objects. The LightWeightNode object contains a subset of the original node object attribute and pre-merges attributes to save RAM. This is handy when you have recipes performing searches with a big result set.
This cookbooks will only help with chef-client RAM consumption. Fixing the server side of the search will require changes to the API.
The amount of RAM saved varies wildly due to Ruby's GC. This really should be fixed on the server side.
In your recipes, use lightweight_node_search function instead of search. Function signature:
lightweight_node_search(query, whitelist)
query- The search querywhitelist- attributes to include in the lightweight node object. This can be an array or a (nested) hash of arrays/strings/symbols
