Arguments
engine A STRING scalar representing the engine name. You can provide either the fully qualified name (e.g., "catalog_name.orca_engine.engine_name"), or just the engine name (e.g., "engine_name") when the system will automatically complete it to the corresponding fully qualified name based on the current catalog setting.

This function can only be called via useOrcaStreamEngine and stops
execution of jobs submitted by DStream::timerEngine.
Examples

def myFunc(x,y,z){
writeLog(x,y,z)

a = "aaa"
b = "bbb"
c = "ccc"
// Submit the steam graph
g = createStreamGraph("timerEngineDemo")
g.source("trade", `id`price, [INT, DOUBLE])
.timerEngine(3, myFunc, a, b, c)
.setEngineName("myJob")
.sink("result")
g.submit()Stop job execution:
useOrcaStreamEngine("myJob", stopTimerEngine)Resume job execution:
