Scheduling Patterns

┌───────────── minute (0-59)
│ ┌───────────── hour (0-23)
│ │ ┌───────────── day of month (1-31)
│ │ │ ┌───────────── month (1-12)

EXAMPLES:
0 7 * * 1-5     → Weekdays at 7:00 AM
0 8 * * 1       → Every Monday at 8:00 AM
0 9 1 * *       → First of every month at 9:00 AM
30 6 * * *      → Every day at 6:30 AM
0 */4 * * *     → Every 4 hours

Best Practices

Schedule Design

guidelines:
  - Consider timezone of recipients
  - Avoid peak hours for data refresh
  - Stagger reports to avoid resource contention
  - Build in buffer time before meetings
  - Use business day calendars for business reports

example_timing:
  executive_reports:
    timing: "7:00 AM local time"
    reason: "Before morning standup"

  operational_reports:
    timing: "6:00 AM local time"
    reason: "Before shift starts"

  financial_reports:
    timing: "After month-end close + 2 days"
    reason: "Data completeness"

Governance Framework

data_classification:
  public:
    distribution: "unrestricted"
    watermark: false
    encryption: false

  internal:
    distribution: "employees_only"
    watermark: true
    encryption: "in_transit"

  confidential:
    distribution: "named_recipients"
    watermark: true
    encryption: "at_rest_and_transit"
    drm: true
    audit_required: true

  restricted:
    distribution: "approval_required"
    watermark: true
    encryption: "at_rest_and_transit"
    drm: true
    audit_required: true
    no_download: true

retention_policy:
  operational: "90 days"
  analytical: "2 years"
  regulatory: "7 years"
  legal_hold: "indefinite"

Error Handling Strategy

class ReportErrorHandler:
    def handle_error(self, error: Exception, context: dict) -> dict:
        error_type = type(error).__name__

        strategies = {
            'DataRefreshTimeout': {
                'action': 'retry',
                'max_retries': 3,
                'backoff': 'exponential',
                'notify': 'ops_team'
            },
            'NoDataAvailable': {
                'action': 'skip',
                'notify': 'report_owner',
                'message': 'Report skipped - no data for period'
            },
            'RecipientInvalid': {
                'action': 'skip_recipient',
                'notify': 'admin',
                'continue': True
            },
            'RenderFailure': {
                'action': 'retry_then_escalate',
                'max_retries': 2,
                'notify': 'dev_team'
            }
        }

        return strategies.get(error_type, {
            'action': 'escalate',
            'notify': 'on_call'
        })

Common Patterns

Dynamic Recipient List

-- Query to generate recipient list based on data
SELECT DISTINCT
    u.email,
    u.first_name,
    u.region,
    'regional_manager' AS role
FROM users u
INNER JOIN sales_data s ON u.region = s.region
WHERE u.role = 'regional_manager'
  AND u.is_active = 1
  AND s.report_date = CURRENT_DATE - 1
  AND s.sales_amount > 0;

Parameterized Reports

report_template:
  name: "Regional Sales Report"
  parameters:
    - name: region
      type: string
      source: "dynamic"
      query: "SELECT DISTINCT region FROM dim_region WHERE is_active = 1"

    - name: date_range
      type: date_range
      default: "last_month"

    - name: include_forecast
      type: boolean
      default: false

  personalization:
    - Filter data by recipient's region
    - Include recipient's name in greeting
    - Highlight recipient's team performance

Burst Report Pattern

# Send personalized version to each recipient
def burst_report(report_template, recipients, data):
    for recipient in recipients:
        # Filter data for this recipient
        filtered_data = filter_data_for_recipient(data, recipient)

        # Generate personalized report
        report = render_report(
            template=report_template,
            data=filtered_data,
            recipient=recipient
        )

        # Send individual report
        send_report(
            to=recipient.email,
            report=report,
            subject=f"Your {report_template.name} - {recipient.region}"
        )

Retry Logic

const executeWithRetry = async (
  operation: () => Promise<any>,
  config: RetryConfig
) => {
  const { maxRetries, backoffMs, retryableErrors } = config;

  for (let attempt = 0; attempt <= maxRetries; attempt++) {
    try {
      return await operation();
    } catch (error) {
      const isRetryable = retryableErrors.includes(error.code);
      const hasRetriesLeft = attempt < maxRetries;

      if (!isRetryable || !hasRetriesLeft) {
        throw error;
      }

      console.log(`Attempt ${attempt + 1} failed, retrying in ${backoffMs[attempt]}ms`);
      await sleep(backoffMs[attempt]);
    }
  }
};

// Usage
await executeWithRetry(
  () => sendReport(report),
  {
    maxRetries: 3,
    backoffMs: [1000, 5000, 15000],
    retryableErrors: ['SMTP_TIMEOUT', 'RATE_LIMITED', 'TEMPORARY_FAILURE']
  }
);

Logging Hooks

const reportHooks = {
  onScheduleTrigger: (reportName: string) => {
    console.log(`[REPORT] Triggered: ${reportName}`);
    metrics.increment('reports.triggered', { report: reportName });
  },

  onDataRefresh: (reportName: string, duration: number) => {
    console.log(`[REPORT] Data refreshed for ${reportName} in ${duration}s`);
    metrics.histogram('reports.refresh_duration', duration);
  },

  onDeliverySuccess: (reportName: string, recipient: string) => {
    console.log(`[REPORT] Delivered ${reportName} to ${recipient}`);
    metrics.increment('reports.delivered');
  },

  onDeliveryFailure: (reportName: string, error: Error) => {
    console.error(`[REPORT] Failed: ${reportName} - ${error.message}`);
    metrics.increment('reports.failed');
    alerting.notify('report_failure', { report: reportName, error });
  }
};

Troubleshooting

Issue	Cause	Solution
Report not sent	Schedule misconfigured	Verify cron and timezone
Empty report	Data not refreshed	Check refresh dependencies
Slow delivery	Large attachment	Compress or send link
Recipient not receiving	Email filtering	Whitelist sender domain
Stale data	Refresh timeout	Increase timeout, optimize query
