CppInstanceHandler terminate

CppInstanceHandler terminate#

package: org.yuanrong.call.

Interface description#

public void terminate() throws YRException#

The member method of the CppInstanceHandler class is used to recycle the cloud-based cpp function instance.

Note

The default timeout for the current kill request is 30 seconds. In scenarios such as high disk load and etcd failure, the kill request processing time may exceed 30 seconds, causing the interface to throw a timeout exception. Since the kill request has a retry mechanism, users can choose not to handle or retry after capturing the timeout exception.

CppInstanceHandler cppInstanceHandler = YR.instance(CppInstanceClass.of("Counter", "FactoryCreate"))
    .setUrn("sn:cn:yrk:default:function:0-opc-opc:$latest")
    .invoke(1);
cppInstanceHandler.terminate();

  • Throws:

    • YRException - If the recycling instance fails, an YRException exception is thrown. For specific errors, see the error message description.

public void terminate(boolean isSync) throws YRException#

The member method of the CppInstanceHandler class is used to recycle cloud-based cpp function instances.

It supports synchronous or asynchronous termination.

Note

When synchronous termination is not enabled, the default timeout for the current kill request is 30 seconds. In scenarios such as high disk load or etcd failure, the kill request processing time may exceed 30 seconds, causing the interface to throw a timeout exception. Since the kill request has a retry mechanism, users can choose not to handle or retry after capturing the timeout exception. When synchronous termination is enabled, this interface will block until the instance is completely exited.

  • Parameters:

    • isSync - Whether to enable synchronization. If true, it indicates sending a kill request with the signal quantity of killInstanceSync to the function-proxy, and the kernel synchronously kills the instance; if false, it indicates sending a kill request with the signal quantity of killInstance to the function-proxy, and the kernel asynchronously kills the instance.

  • Throws:

    • YRException - If the recycling instance fails, an YRException exception is thrown. For specific errors, see the error message description.
