+  title: Allow partial results by default in ES|QL
+  area: ES|QL
+  details: >-
+    In earlier versions of {es}, ES|QL would fail the entire query if it encountered any error. ES|QL now returns partial results instead of failing when encountering errors.
+
+  impact: >-
+    Callers should check the `is_partial` flag returned in the response to determine if the result is partial or complete. If returning partial results is not desired, this option can be overridden per request via an `allow_partial_results` parameter in the query URL or globally via the cluster setting `esql.query.allow_partial_results`.
