But timeouts are not always effective since they may not activate until a malicious query has already consumed excessive resources. Timeout requirements will differ by API and data fetching mechanism; there isn't one timeout value that will work across the board.\n\nAt the application level, timeouts can be added for queries and resolver functions. This option is usually more effective since the query/resolution can be stopped once the timeout is reached. GraphQL does not natively support query timeouts so custom code is required. See this blog post for more about using timeouts with GraphQL or the two examples below.\n\n_JavaScript Timeout Example_\n\nCode snippet from this SO answer\n\nBounded code example (external data; do not execute automatically):\n```javascript\nrequest.incrementResolverCount =  function () {\n    var runTime = Date.now() - startTime;\n    if (runTime > 10000) {  // a timeout of 10 seconds\n      if (request.logTimeoutError) {\n        logger('ERROR', `Request ${request.uuid} query execution timeout`);\n      }\n      request.logTimeoutError = false;\n      throw 'Query execution has timeout. Field resolution aborted';\n    }\n    this.resolverCount++;\n  };\n```\n\n_Java Timeout Example using Instrumentation_\n\nBounded code example (external data; do not execute automatically):\n```java\npublic class TimeoutInstrumentation extends SimpleInstrumentation {\n    @Override\n    public DataFetcher<?> instrumentDataFetcher(\n            DataFetcher<?> dataFetcher, InstrumentationFieldFetchParameters parameters\n    ) {\n        return environment ->\n            Observable.fromCallable(() -> dataFetcher.get(environment))\n                .subscribeOn(Schedulers.computation())\n                .timeout(10, TimeUnit.SECONDS)  // timeout of 10 seconds\n                .blockingFirst();\n    }\n}\n```\n\nAnother option to add a timeout that is usually easier is adding a timeout on an HTTP server (Apache/httpd, nginx), reverse proxy, or load balancer. However, infrastructure timeouts are often inaccurate and can be bypassed more easily than application-level ones.\n\nAttribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
