Links Recommendations Service

• https://phabricator.wikimedia.org/T252822
• GL: Idea is to store a blob of wikitext for every page
• What’s best practice for storing derived data that would be invalidated by every edit?
• TS: similar to data pipelines like page content service
• TS: similar to links tables
• DK: have some kind of “slow” page_props.
• TS: will lead to race conditions
• GL: wikitext for every page may mean considerable volume
• DK: might fit the generalized parser cache. Would have to be even more generalized.
• DK: Dependency Engine may solve part of this, though not storage

EventStream needs timestamps

• DA: EventStream needs timestamps, which some event hooks are missing.
• Pass LogEntry objects to relevant hooks?
• DK: adding parameters to hooks is a breaking interface change.
• TS: hook deprecation mechanism should take care of this.
• DA: ArticleDelete hook exposes it already, works well, getTimestamp. Can do for others.
• TT: In light of T212482, be sure to type against a narrower getter-only interface as the set/save methods must not be used at that point.
• DK: That’s a good idea also to enable async hooks, safe to serialize value objects. NonSerializable trait may be useful https://gerrit.wikimedia.org/r/c/mediawiki/core/+/625612
