Database-backed storage backend

Using a SQL DBMS instead of the default in-memory store enables chp to be replicated in a High Availability scenario.

To use a SQL DBMS as the storage backend:

1. Install DBMS support

$ pip install configurable-http-proxy[sqla]

2. Set the CHP_DATABASE_URL env var to any db URL supported by SQLAlchemy. The default is sqlite:///chp.sqlite.

$ export CHP_DATABASE_URL="sqlite:///chp.sqlite"
$ configurable-http-proxy --storage-backend configurable_http_proxy.dbstore.DatabaseStore

3. Optionally you may set the table name by setting the CHP_DATABASE_TABLE. The default is 'chp_routes'

$ export CHP_DATABASE_TABLE="chp_routes"
