**Type of activity:** Pre-scheduled session. Unconference would also be OK.
**Main topic:** https://www.mediawiki.org/wiki/Wikimedia_Developer_Summit/2017/How_to_manage_our_technical_debt / https://www.mediawiki.org/wiki/Wikimedia_Developer_Summit/2017/Handling_wiki_content_beyond_plaintext
== The problem ==
The way MediaWiki stores information in a relational database is not very efficient. In some respects are are reaching the limits of the current design. We need to explore options to address this issue, like normalization, denormalization, partitioning, as well as alternative storage technologies.
Concrete problems include the size of the revision table and the performance impact of redundant storage of page titles in link tables.
== Expected outcome ==
* A roadmap proposal for improving storage scalability
== Current status of the discussion ==
No centralized discussion, but the issue as been brought up in the context of various discussions, see below.
