Initiative Vision

< Initiatives

Vision:
  • To be able to install MediaWiki with a database backend other than those supported in core
  • To be able to develop additional database backends for MediaWiki and deliver them in extensions
Stakeholder(s):
  • Operators of MediaWiki installations that need to deploy to an environment where they must use a database other than those supported in core (for example, Microsoft SQL Server or Oracle)
  • Developers of alternative database functionality for MediaWiki who need an extension interface for their work.
Problem:
  • Support for Oracle and Microsoft SQL Server was removed from core in the summer of 2019.
  • This was done to reduce the maintenance burden in core, especially since it is not possible to run tests against these proprietary software systems.
  • This was a regression for those using MediaWiki with those databases and limits options for others who may want to deploy functionality of other alternative database systems.
Solution:
  • Develop an extension interface in core to allow alternative databases to be used with MediaWiki.
  • Support installing MediaWiki with a database that is provided by an extension.
Aligned Goals:
  • Code Health
Success Metrics:
  • Ensure that there is no degradation in performance caused by using a database provided through an extension.
  • Ensure that there is no degradation in performance caused by the extension interface code while using a database provided in core.
  • Develop at least one proof-of-concept database extension.
