In a map/reduce script is there any way to pass a small amount of data (like a single array) directly from the getinputdata function to the summarize function?

Do the

map

and/or

reduce

stages need this Array as well? If not, and it's not too expensive, you could just move the retrieval of the Array to the

summarize

stage directly.

Nope just summarize. I'm doing a suiteql query in the getinputdata method to pull vendors i need to make active, but want to pass this array of vendor ids to the summarize method to then make them inactive again

You can send those IDs as keys to your summary stage from reduce, then build your array there and do what you need to do.

const myVendors = [];
summaryContext.output.iterator().each(function (key, value){
    const sVendorId = key;
    myVendors.push(sVendorId);
    return true;
});

Your reduce could look like this:

reduceContext.write({key: sVendorId, value: ''});

It's about 400 ids in a single array, I was looking into building out a file but this seems a bit better scoped to me? Thank you for the suggestion alien

No, pass your data down to reduce, there you pass your data to summary.

oh, unfortunately I don't think that would work. The idea is to pass from getInputData directly to Summary, there's no use for this data in the reduce function. Thanks though!

As far as I know there is no way to pass data from getInput to Summary, is not the way it works, by design it does not work like that.

Ha I'm currently (inheriting) writing some logic that needs to activate then inactivate records. I have one M/R containing the activation logic, which triggers another M/R containing the actual processing, which subsequently triggers a M/R containing the inactivation step. I use the

reduce

stage instead of

summarize

to do the active toggling because

summarize

is not parallelized

That's the way I'm leaning/working on eric (writing to a file), yeah the 3 m/r would be a lot... this is only one of 4 m/rs i'm writing for my accounting team even

FWIW I'm passing the record IDs between my two M/Rs using files.

If the id's are unique, couldn't you just call a SuiteLet that does the logic you're talking about, passing it the id of the record you need processing, less jobs using processors, closer to real-time updates. Just a thought, a thought without the full picture of course 😉

Thanks for the sugestion NElliott, the problem is that I need to make the vendors active in the getinputdata stage and then active again in the summary stage, so it's two steps and I need the vendor ids to be available at both steps
