clintropolis opened a new pull request, #19374: URL: https://github.com/apache/druid/pull/19374
### Description Adds a new family of retention rules, `loadPartialByPeriod`, `loadPartialByInterval`, `loadPartialForever`, laying the groundwork for partial loading of V10 segment projections on historicals. This PR includes the rule classes, matcher abstraction, and cascade semantics only; the coordinator plumbing, wire format, and historical-side partial load path are deferred to follow-up work. changes: * adds `PartialLoadRule` abstract class to capture load rules that should partially load a segment on some tier * adds `IntervalPartialLoadRule, `ForeverPartialLoadRule`, and `PeriodPartialLoadRule` implementations to mirror non-partial load rules * adds `PartialLoadMatcher` interface to match and select what to partial load * adds `ExactProjectionPartialLoadMatcher` and `WildcardProjectionPartialLoadMatcher` to do partial loading of projections * adds `CannotMatchBehavior` enum to describe behavior of `PartialLoadRule` when `PartialLoadMatcher` is unable to match a segment * since partial loading is not available yet, partial rules function as regular load rules until follow-up work * tests -- This is an automated message from the Apache Git Service.
