> URL: https://issues.apache.org/jira/browse/COUCHDB-747
> Project: CouchDB
> Issue Type: Improvement
> Components: Database Core
> Affects Versions: 0.11
> Reporter: Adam Kocoloski
> Fix For: 1.1

>
> We use proplists:get_value to inspect JSON Objects in Erlang. I think we
> should switch to lists:keysearch. It's a BIF and appears to be 2-3x faster
> than proplists for a wide class of lookups. Here's a microbenchmark:
> http://gist.github.com/374220
> The get_value() functions in that gist provide a wrapper around keysearch to
> give it the same interface as proplists:get_value. The only incompatibility
> in the wrapper is that proplists will find atoms (instead of tuples) in the
> list, while keysearch will ignore them. But our JSON term format doesn't
> contain any standalone atoms, so this is not an issue for us.
