Hi, everyone! I’d appreciate a review on this pull request when someone has a moment: github.com/StarRocks/starrocks/pull/80115 What: It adds an opt-in session variable,

enable_gather_fragment_child_affinity

(default

false

). When it’s on, the gather/result fragment is placed on a BE already used by its child fragments instead of being picked by global round-robin. Why: In shared-nothing clusters that use

labels.location

for physical isolation, the result fragment of a SELECT can currently land on a BE outside the tenant’s label (github.com/StarRocks/starrocks/issues/79937). Scope: Changes

RemoteFragmentAssignmentStrategy

and

SessionVariable

, with unit tests and docs. Default behavior is unchanged. Thanks!
