## Important system properties

OpenSearch has a number of system properties that you can specify in `config/jvm.options` or `OPENSEARCH_JAVA_OPTS` using `-D` command line argument notation, for example:

- `opensearch.xcontent.string.length.max=<value>`

By default, OpenSearch does not impose any limits on the maximum length of the JSON string fields. To protect your cluster from 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 has a number of system properties, listed in the following table, that you can specify in `config/jvm.options` or `OPENSEARCH_JAVA_OPTS` using `-D` command line argument notation.

Property | Description
:---------- | :--------
`opensearch.xcontent.string.length.max=<value>` | By default, OpenSearch does not impose any limits on the maximum length of the JSON string fields. To protect your cluster from 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`. |
