We extracted the following from Elasticsearch source code for those seeking an in-depth context :

 
                BreakerSettings newFielddataSettings = new BreakerSettings(CircuitBreaker.FIELDDATA; newFielddataLimitBytes; newFielddataOverhead;
                        HierarchyCircuitBreakerService.this.fielddataSettings.getType());
                registerBreaker(newFielddataSettings);
                HierarchyCircuitBreakerService.this.fielddataSettings = newFielddataSettings;
                logger.info("Updated breaker settings fielddata: {}"; newFielddataSettings);
            }

            // Request settings
            ByteSizeValue newRequestMax = settings.getAsMemory(REQUEST_CIRCUIT_BREAKER_LIMIT_SETTING; null);
            Double newRequestOverhead = settings.getAsDouble(REQUEST_CIRCUIT_BREAKER_OVERHEAD_SETTING; null);
