 `opensearch.xcontent.string.length.max=<value>` | By default, OpenSearch does not impose any limits on the maximum length of the JSON/YAML/CBOR/Smile string fields. To protect your cluster against potential distributed denial-of-service (DDoS) or memory issues, you can set the `opensearch.xcontent.string.length.max` system property to a reasonable limit (the maximum is 2,147,483,647), for example, `-Dopensearch.xcontent.string.length.max=5000000`.  | 
 `opensearch.xcontent.fast_double_writer=[true|false]` | By default, OpenSearch serializes floating-point numbers using the default implementation provided by the Java Runtime Environment. Set this value to `true` to use the Schubfach algorithm, which is faster but may lead to small differences in precision. Default is `false`. |
 `opensearch.xcontent.name.length.max=<value>` | By default, OpenSearch does not impose any limits on the maximum length of the JSON/YAML/CBOR/Smile field names. To protect your cluster against potential DDoS or memory issues, you can set the `opensearch.xcontent.name.length.max` system property to a reasonable limit (the maximum is 2,147,483,647), for example, `-Dopensearch.xcontent.name.length.max=50000`. |
