reduceContext.isRestarted
|
Property Description |
Indicates whether the reduce(reduceContext) function has run before for the current key and values. For an overview of events that can cause a restart, see System Response After a Map/Reduce Interruption. When the reduce function restarts for a key-value pair, any data it wrote last time is deleted. Some logic might have run before it was interrupted, so if reduceContext.isRestarted is true, your script should take steps to avoid duplicate processing. For examples, see Adding Logic to Handle Map/Reduce Restarts. For examples, see Adding Logic to Handle Map/Reduce Restarts. Related properties include reduceContext.executionNo and reduceContext.errors. |
