Previously, the development environment only needed to connect to the English wikipedia replica database, so it was enough to set up a ssh tunnel and connect through that. However, in future versions of the code, we will need to connect to a variety of wiki replica database, in order to select
links
andlang_links
. So, for example, for French wikipedia, we will need to connect tofrwiki.analytics.db.svc.wikimedia.cloud
. In fact, we will need to connect to all db replicas for all wikipedia languages.This code will not be used in production, it is only for development. In production, the
*.analytics.db.svc.wikimedia.cloud
hosts are all reachable from the production cloud VPS server. For local testing and debugging, we need the SOCKS proxy.
