Scheduled Tasks & Batch Processing

Comprehensive patterns for scheduled tasks, batch jobs, and recurring processes using timer events.

Overview

Scheduled tasks enable:

• ✅ Automated batch processing at specific times
• ✅ Recurring business processes (daily, weekly, monthly)
• ✅ Data synchronization and ETL jobs
• ✅ Report generation on schedule
• ✅ Cleanup and maintenance tasks

Pattern 1: Daily Batch Processing

Process data daily at scheduled time:

<!-- Start every day at 2 AM -->
<bpmn:startEvent id="DailyBatchStart" name="Daily Batch - 2 AM">
  <bpmn:timerEventDefinition>
    <bpmn:timeCycle>0 2 * * *</bpmn:timeCycle>
  </bpmn:timerEventDefinition>
</bpmn:startEvent>

<!-- Prepare batch data -->
<bpmn:scriptTask id="PrepareBatchData" name="Prepare Batch Data">
  <bpmn:script>
    // Get yesterday's date
    var yesterday = new Date();
    yesterday.setDate(yesterday.getDate() - 1);
    var batchDate = yesterday.toISOString().split('T')[0];
    
    context.batchDate = batchDate;
    context.batchStartTime = new Date().toISOString();
    
    logger.info('Starting daily batch for ' + batchDate);
    
    // Get data to process
    var dataResult = BankLingo.ExecuteCommand('GetBatchData', {
      date: batchDate,
      type: 'transactions'
    });
    
    context.batchItems = dataResult.result.items;
    context.batchCount = dataResult.result.items.length;
    
    logger.info('Batch contains ' + context.batchCount + ' items');
    
    return {
      batchDate: batchDate,
      itemCount: context.batchCount
    };
  </bpmn:script>
</bpmn:scriptTask>

<!-- Check if batch has data -->
<bpmn:exclusiveGateway id="HasData" name="Has Data?"/>

<bpmn:sequenceFlow sourceRef="HasData" targetRef="ProcessBatch">
  <bpmn:conditionExpression>${context.batchCount > 0}</bpmn:conditionExpression>
</bpmn:sequenceFlow>

<bpmn:sequenceFlow sourceRef="HasData" targetRef="NoBatchData">
  <bpmn:conditionExpression>${context.batchCount === 0}</bpmn:conditionExpression>
</bpmn:sequenceFlow>

<!-- Process batch items in parallel -->
<bpmn:callActivity id="ProcessBatch" 
                   name="Process Batch Items"
                   calledElement="ProcessSingleItem">
  <bpmn:multiInstanceLoopCharacteristics isSequential="false">
    <custom:property name="collection" value="context.batchItems"/>
    <custom:property name="elementVariable" value="currentItem"/>
    <custom:property name="aggregationVariable" value="batchResults"/>
  </bpmn:multiInstanceLoopCharacteristics>
</bpmn:callActivity>

<!-- Generate batch report -->
<bpmn:scriptTask id="GenerateBatchReport" name="Generate Report">
  <bpmn:script>
    var endTime = new Date().toISOString();
    var startTime = new Date(context.batchStartTime);
    var duration = (new Date(endTime) - startTime) / 1000; // seconds
    
    // Calculate statistics
    var successCount = context.batchResults.filter(r => r.success).length;
    var errorCount = context.batchResults.filter(r => !r.success).length;
    
    context.batchDuration = duration;
    context.successCount = successCount;
    context.errorCount = errorCount;
    
    logger.info('Batch complete: ' + successCount + ' success, ' + errorCount + ' errors, ' + duration + 's');
    
    // Generate report
    var report = BankLingo.ExecuteCommand('GenerateBatchReport', {
      batchDate: context.batchDate,
      totalCount: context.batchCount,
      successCount: successCount,
      errorCount: errorCount,
      duration: duration,
      results: context.batchResults
    });
    
    return {
      reportId: report.result.reportId
    };
  </bpmn:script>
</bpmn:scriptTask>

<!-- Send report notification -->
<bpmn:sendTask id="SendReportEmail" name="Send Report Email">
  <bpmn:extensionElements>
    <custom:properties>
      <custom:property name="messageType" value="email"/>

    </custom:properties>
  </bpmn:extensionElements>
</bpmn:sendTask>

<!-- No data path -->
<bpmn:scriptTask id="NoBatchData" name="Log No Data">
  <bpmn:script>
    logger.info('No batch data for ' + context.batchDate);
  </bpmn:script>
</bpmn:scriptTask>

<bpmn:endEvent id="BatchComplete" name="Batch Complete"/>

Pattern 2: Weekly Reporting

  <bpmn:timerEventDefinition>
    <bpmn:timeCycle>0 9 * * 1</bpmn:timeCycle>

  <bpmn:script>
    // Get previous week (Monday to Sunday)
    var today = new Date();
    var lastMonday = new Date(today);
    lastMonday.setDate(today.getDate() - 7); // Last Monday
    
    var lastSunday = new Date(lastMonday);
    lastSunday.setDate(lastMonday.getDate() + 6); // Last Sunday
    
    context.weekStartDate = lastMonday.toISOString().split('T')[0];
    context.weekEndDate = lastSunday.toISOString().split('T')[0];
    context.weekNumber = getWeekNumber(lastMonday);
    
    logger.info('Generating weekly report for week ' + context.weekNumber + 
                ' (' + context.weekStartDate + ' to ' + context.weekEndDate + ')');
    
    return {
      weekNumber: context.weekNumber,
      startDate: context.weekStartDate,
      endDate: context.weekEndDate
    };
    
    function getWeekNumber(date) {
      var d = new Date(Date.UTC(date.getFullYear(), date.getMonth(), date.getDate()));
      var dayNum = d.getUTCDay() || 7;
      d.setUTCDate(d.getUTCDate() + 4 - dayNum);
      var yearStart = new Date(Date.UTC(d.getUTCFullYear(),0,1));
      return Math.ceil((((d - yearStart) / 86400000) + 1)/7);
    }
  </bpmn:script>
</bpmn:scriptTask>

<!-- Generate reports in parallel -->
<bpmn:scriptTask id="GetReportTypes" name="Get Report Types">
  <bpmn:script>
    context.reportTypes = [
      { type: 'TRANSACTIONS', name: 'Transaction Summary' },

    <custom:property name="elementVariable" value="reportType"/>
    <custom:property name="aggregationVariable" value="generatedReports"/>
  </bpmn:multiInstanceLoopCharacteristics>
</bpmn:callActivity>

<!-- Combine and distribute reports -->
<bpmn:scriptTask id="CombineReports" name="Combine Reports">
  <bpmn:script>
    logger.info('Combining ' + context.generatedReports.length + ' reports');
    
    var reportPackage = BankLingo.ExecuteCommand('CreateReportPackage', {
      weekNumber: context.weekNumber,
      startDate: context.weekStartDate,
      endDate: context.weekEndDate,
      reports: context.generatedReports
    });
    
    context.reportPackageId = reportPackage.result.packageId;
    context.reportPackageUrl = reportPackage.result.downloadUrl;
    
    return {
      packageId: context.reportPackageId
    };
  </bpmn:script>
</bpmn:scriptTask>

Best Practices

✅ Do This

<!-- ✅ Use appropriate schedule frequency -->
<!-- Hourly for critical sync -->
<bpmn:timeCycle>0 * * * *</bpmn:timeCycle>

<!-- Daily for batch jobs -->
<bpmn:timeCycle>0 2 * * *</bpmn:timeCycle>

<!-- ✅ Run during off-peak hours -->
<!-- 2 AM for intensive processing -->

<!-- ✅ Log batch execution -->
logger.info('Batch started: ' + batchDate);

<!-- ✅ Send completion notifications -->
<!-- Email on success/failure -->

<!-- ✅ Use multi-instance for parallel processing -->
<bpmn:multiInstanceLoopCharacteristics isSequential="false">

<!-- ✅ Handle empty batches gracefully -->
if (items.length === 0) {
  logger.info('No items to process');
}

<!-- ✅ Track batch statistics -->
context.successCount = ...;
context.errorCount = ...;
context.duration = ...;

❌ Don't Do This

<!-- ❌ Very frequent schedules -->
<bpmn:timeCycle>R/PT1M</bpmn:timeCycle>  <!-- Every minute - use event-driven instead -->

<!-- ❌ No error handling -->
<!-- Always add error boundaries and notifications -->

<!-- ❌ Processing during peak hours -->
<bpmn:timeCycle>0 12 * * *</bpmn:timeCycle>  <!-- Noon - use off-peak times -->

<!-- ❌ No batch size limits -->
<!-- Always paginate or limit batch sizes -->

<!-- ❌ Sequential processing of large batches -->
<bpmn:multiInstanceLoopCharacteristics isSequential="true">
<!-- Use parallel for large batches -->

Performance Optimization

Batch Size Management

// ✅ Process in manageable chunks
var allItems = getItems(); // 10,000 items
var batchSize = 100;
var batches = [];

for (var i = 0; i < allItems.length; i += batchSize) {
  batches.push(allItems.slice(i, i + batchSize));
}

context.batches = batches;
context.batchCount = batches.length;

Parallel Processing

<!-- ✅ Process multiple items in parallel -->
<bpmn:callActivity id="ProcessItems" calledElement="ProcessItem">
  <bpmn:multiInstanceLoopCharacteristics isSequential="false">
    <custom:property name="collection" value="context.items"/>
    <custom:property name="elementVariable" value="item"/>
  </bpmn:multiInstanceLoopCharacteristics>
</bpmn:callActivity>

Error Isolation

// ✅ Continue on individual failures
try {
  processItem(item);
  return { success: true, itemId: item.id };
} catch (error) {
  logger.error('Failed to process item ' + item.id + ': ' + error.message);
  return { success: false, itemId: item.id, error: error.message };
}
