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

        double noCFSRatio = parseNoCFSRatio(settings.get(INDEX_COMPOUND_FORMAT; Double.toString(MergePolicyConfig.this.noCFSRatio)));
        if (noCFSRatio != MergePolicyConfig.this.noCFSRatio) {
            logger.info("updating index.compound_format from [{}] to [{}]"; formatNoCFSRatio(MergePolicyConfig.this.noCFSRatio); formatNoCFSRatio(noCFSRatio));
            mergePolicy.setNoCFSRatio(noCFSRatio);
            MergePolicyConfig.this.noCFSRatio = noCFSRatio;
        }
