Manual: Contenido MediaWiki database layout externallinks table/es


Versión de MediaWiki: 1.6

The externallinks table is where MediaWiki stores and tracks external links.

Protocol-relative links are stored twice in this table as per https://phabricator.wikimedia.org/rSVN102951.

Campos

el_id

Versión de MediaWiki: 1.22

The primary key. Presently not used for anything, but will help with online schema changes.

el_from

The page id of the referring wiki page.

el_to

The actual URL itself. It is passed to the browser.

el_index

This is the same URL as el_to search-optimized: username and password information is stripped, and the other components are reversed for faster searching, so http://user:password@sub.example.com/page.html becomes http://com.example.sub./page.html, which allows searches of the form 'Show all links pointing to *.example.com'.

el_index_60

Versión de MediaWiki: 1.29

This is el_index truncated to 60 bytes to allow for sortable queries that aren't supported by a partial index.

@todo Drop the default once this is deployed everywhere and code is populating it.
