## Summary This PR makes `rest_query_default_row_size_limit` the hard upper bound for REST and Grafana query responses. ## Changes - Cap user-provided REST `rowLimit` / `row_limit` with `rest_query_default_row_size_limit`. - Apply the same limit to Grafana variables, node, and expression endpoints instead of passing an unlimited `0`. - Enforce the cap in v2 fast-last cache-hit responses, which previously built the response directly. - Centralize row-limit calculation and exceeded-limit response handling in `QueryRowLimitUtils`. - Update OpenAPI/config comments to describe the setting as a maximum response row limit. - Add focused regression tests for hard-cap resolution and exact-limit dataset handling. ## Validation - `mvn spotless:apply -pl external-service-impl/rest` - `mvn test -pl external-service-impl/rest -Dtest=QueryRowLimitUtilsTest,QueryDataSetHandlerTest` - `mvn test-compile -pl external-service-impl/rest -P with-zh-locale -DskipTests` - `mvn test-compile -pl external-service-impl/rest-openapi -DskipTests` - `git diff --check` -- This is an automated message from the Apache Git Service.
