Update $wgInterwikiCache docs and remove outdated CDB-related code
Closed, ResolvedPublic
Actions

Description

The CDB data format has not been supported by $wgInterwikiCache since change 760695 but references to it remain in various places, including the documentation for the setting itself. There is also still code and complexity in the structure of the lookup service and the dumpInterwiki.php script to accomodate this now non-existent feature.

Update $wgInterwikiCache docs in source code.
Simplify MW's ClassicInterwikiLookup class where possible, and updated or improve outdated class docs in source code.
Simplify WMF's dumpInterwiki.php script and correct its outdated docs.
Review or update https://www.mediawiki.org/wiki/Interwiki_cache.
Update https://www.mediawiki.org/wiki/Manual:Performance_tuning.
