Using TypeScript, write the summary function of a Map Reduce that will log out all errors from getInputData, map and reduce steps

AI generated answer (using internal Slack threads):

Based on the conversations, here is a TypeScript function that summarizes the Map Reduce and logs out all errors from getInputData, map, and reduce steps:

typescript
function summarize(summary: any) {
    let errors = [];

    // Check if there are errors in the getInputData stage
    if (summary.inputSummary.error) {
        errors.push(summary.inputSummary.error);
    }

    // Check if there are errors in the map stage
    summary.mapSummary.errors.iterator().each((key: any, error: any) => {
        errors.push(error);
        return true; // Continue iterating
    });

    // Check if there are errors in the reduce stage
    summary.reduceSummary.errors.iterator().each((key: any, error: any) => {
        errors.push(error);
        return true; // Continue iterating
    });

    // Log all errors
    for (let error of errors) {
        log.error('Error', error);
    }
}

This function first checks if there are any errors in the getInputData stage. If there are, it adds them to the

errors

array. It then iterates over the errors in the map and reduce stages, adding each error to the

errors

array. Finally, it logs all the errors. Please note that the

iterator().each()

function requires a callback that returns a truthy value to continue iterating. In this case, we return

true

to ensure that all errors are iterated over. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
