In a MapReduce script's map function, how do I write a search result to the context value, using a separate integer as the key?

AI generated answer (using internal Slack threads):

In a MapReduce script's map function, you can write a search result to the context value using a separate integer as the key by using the

context.write

function. The

context.write

function takes two parameters: the key and the value. The key can be an integer or a string, and the value is the data you want to pass to the reduce stage. Here is a basic example of how you can use it:

javascript
function map(context) {
    // Parse the search result
    var searchResult = JSON.parse(context.value);

    // Write the search result to the context with an integer as the key
    context.write(1, searchResult);
}

In this example,

1

is the key and

searchResult

is the value. All the search results written with the same key will be grouped together and passed to the reduce stage. Remember, the key you use in

context.write

determines how the data is grouped. If you use a unique key for each search result, each result will be processed separately in the reduce stage. If you use the same key for multiple results, those results will be grouped together and processed together in the reduce 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. ******
