what if I got two different reduce and summary in different script, which will be trigger?

AI generated answer (using internal Slack threads):

In a Map/Reduce script, the

summarize

stage should always execute, even if there is no output in the

reduce

stage. This is because the

summarize

stage is designed to provide a summary of the script's execution, regardless of the output of the

reduce

stage. If you have two different

reduce

and

summary

in different scripts, the one that will be triggered depends on the order of execution of the scripts. If the scripts are independent, they will execute based on their scheduling or triggering event. If one script is called within another (like a Map/Reduce script calling another Map/Reduce script at the summary stage), the called script's

reduce

and

summary

will execute after the calling script's stages. For example, you can create a task to call another Map/Reduce script in the

summary

stage like this:

javascript
task.create({
    taskType: task.TaskType.MAP_REDUCE,
    scriptId: 'customscript1',
    deploymentId: 'customdeploy1'
}).submit();

To access the values returned from the

Reduce

stage in the

Summary

stage, you can use

reduceContext.write

and

summaryContext.output

. For instance, if you have journal entries created in the

Reduce

stage and you want to have a summary list of their IDs in the summary, you can write the IDs in the

Reduce

stage and then access them in the

Summary

stage. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
