6 MB

Valid payload size of invocation request body (asynchronous invocation)

256 KB

  • Valid payload size of invocation response body (synchronous invocation): The returned character string or the JSON character string of the serialized response body is less than or equal to 6 MB by default. The actual data size varies depending on the backend settings of FunctionGraph. The backend determines the size of the serialized data with a byte-level deviation. The actual valid payload size is 6 MB ± 100 bytes.
  • You are not advised to invoke a function whose execution time exceeds 90s on the FunctionGraph console. If you need to invoke such a function, use asynchronous invocation.
