> Hide internal config details from other applications
> ----------------------------------------------------
>
> Key: COUCHDB-2629
> URL: https://issues.apache.org/jira/browse/COUCHDB-2629
> Project: CouchDB
> Issue Type: Bug
> Security Level: public(Regular issues)
> Components: Database Core
> Reporter: Russell Branca
>
> Throughout the code base we do things like `config:get("couch_httpd_auth",
> "authentication_db", "_users")` which exposes internal details to other
> applications that don't need to be aware of the particulars. This duplicates
> code unnecessarily and causes problematic typos to go unnoticed like in
> COUCHDB-2628.
> One possible approach that I'm a fan of is to go into the application
> responsible for relevant config value, and add a function to hide the
> details. For instance, this is done in `cassim_metadata_cache:metadata_db`:
> https://github.com/apache/couchdb-cassim/blob/windsor-merge/src/cassim_metadata_cache.erl#L58-L59
