There was a problem hiding this comment.
I love the essence the library is getting, but it's too complex. A simple metric: for performing cached queries to CARTO the project has 38 files.
Also a general comment, we are trying to change the use of the src folder, we should call it longitude.
About the queries: we need to decide if we are going to use Pyscopg2 only or SQLAlchemy and check how to bindings are implemented for starting to use it with CARTO. The bindings in CARTO are going to take a lot, but the use of query methods in this library needs to be the same for every DB.
Well, to perform cached queries a library user needs to import two modules (one for cache, one for data source). Then, from those modules it could be necessary to import configuration classes, but it is not mandatory. The 38 files (or so) are about structure, tests, sample proyects and other development stuff; if project size is a concern, we can deploy only the pure core scripts and those are around 10 or so.
For me this is sort of confusing as "longitude" is the root folder. What would be that use regarding
My plan is to do this totally transparent. I still have to decide if SQLAlchemy will be a configurable aspect of the Psycopg2 data source or if I will create two different data sources: one with, one withtout SQLAlchemy. Anyhow, the CARTO thing is irrelevant at this level as bindings are resolved inside each specific query method implementation.

EnvironmentConfiguration is now a domain class that exposes a single get(key) method.
It will parse environment variables in the form LONGITUDE__PARENT_OBJECT__CHILD_OBJECT__VALUE=42 as {'parent_object': {'child_object': {'value': 42 } }
It also allows to recover the values using nested keys ('.' is the joiner): Config.get('parent_object.child_object.value') returns 42 (as integer).
Also, if a value can be parsed as integer, it will be parsed.
