Can we track the progress of the batch job?

Yes — every batch job is represented by an AsyncApexJob record. You can monitor progress through the Setup → Apex Jobs UI or query the record directly with SOQL.

The JobId is your handle

Id jobId = Database.executeBatch(new MyBatch(), 200);

That JobId is the primary key into AsyncApexJob. Save it, log it, surface it to the user — anywhere you need to refer to “that specific run.”

Useful fields to query

SELECT Id, ApexClass.Name, Status, JobType,
       TotalJobItems, JobItemsProcessed, NumberOfErrors,
       ExtendedStatus, CreatedDate, CompletedDate, CreatedBy.Email
FROM AsyncApexJob
WHERE Id = '7071g00000abcde'

JobItemsProcessed / TotalJobItems is your progress percentage.

Build a status helper

public class BatchMonitor {
    public class BatchStatus {
        public String status;
        public Integer percent;
        public Integer errors;
        public String error;
    }

    public static BatchStatus check(Id jobId) {
        AsyncApexJob job = [
            SELECT Status, TotalJobItems, JobItemsProcessed,
                   NumberOfErrors, ExtendedStatus
            FROM AsyncApexJob WHERE Id = :jobId
        ];
        BatchStatus s = new BatchStatus();
        s.status = job.Status;
        s.percent = (job.TotalJobItems > 0)
            ? (job.JobItemsProcessed * 100 / job.TotalJobItems)
            : 0;
        s.errors = job.NumberOfErrors;
        s.error = job.ExtendedStatus;
        return s;
    }
}

A Lightning component can call this every few seconds to render a progress bar.

Where to look in the UI

The Apex Jobs page links to per-job detail with chunk-by-chunk error messages.

What “Completed” doesn’t mean

A status of Completed only means the job finished its lifecycle. Some chunks may have failed — check NumberOfErrors. A defensive monitoring check:

AsyncApexJob job = [SELECT Status, NumberOfErrors FROM AsyncApexJob WHERE Id = :jobId];
Boolean fullSuccess = (job.Status == 'Completed' && job.NumberOfErrors == 0);

Errors in detail

AsyncApexJob.ExtendedStatus shows the last error message. To see all error messages with their records, query BatchApexErrorEvent (a Platform Event) or attach a custom error log inside your batch’s execute:

catch (Exception e) {
    insert new Batch_Error__c(
        Job_Id__c = ctx.getJobId(),
        Message__c = e.getMessage(),
        Stack_Trace__c = e.getStackTraceString()
    );
}

Common interview follow-ups

• Are jobs deleted from AsyncApexJob? — Yes, after 7 days. For longer audit, log your own records.
• Can a user without admin see Apex Jobs? — Needs View Setup and Configuration + Author Apex depending on what they need to see.
• How fast is the status updated? — Near real-time; JobItemsProcessed increments as chunks complete.
