Batch Processing

A data processing approach that collects events over a defined time period and processes them together as a group, typically on hourly or daily schedules, optimized for throughput and complex computations.

Also known as: batch job, scheduled processing

Why It Matters

Batch processing handles the heavy analytical lifting that real-time streaming cannot efficiently perform. Calculating customer lifetime values, rebuilding recommendation models, generating daily executive reports, and running complex aggregations across millions of records are all tasks better suited to batch processing.

Batch jobs are also more cost-efficient for large-scale data processing. Instead of maintaining always-on streaming infrastructure, batch jobs spin up resources when needed, process the data, and shut down. For many analytics use cases where hourly or daily freshness is sufficient, batch processing delivers the same insights at a fraction of the infrastructure cost.

Reliable batch processing is the foundation of your reporting cadence. When stakeholders expect updated dashboards every morning, it is the overnight batch jobs that aggregate, transform, and load the data that powers those dashboards.

Industry Applications

E-commerce

A fashion retailer runs nightly batch jobs that calculate product affinity scores, update customer segments, and regenerate personalized recommendation lists. These feed into the next day's email campaigns and on-site personalization.

SaaS

A B2B analytics platform runs hourly batch jobs that aggregate usage data across thousands of customer accounts, calculate health scores, and update the customer success dashboard. Daily batch jobs rebuild predictive churn models with the latest behavioral data.

How to Track in KISSmetrics

KISSmetrics uses a combination of real-time and batch processing internally. For your own batch processing needs, schedule regular exports of KISSmetrics data to your data warehouse where batch transformation jobs can calculate derived metrics, build cohort tables, and prepare data for machine learning models.

Common Mistakes

  • -Not implementing retry logic for failed batch jobs, causing missing data that requires manual intervention
  • -Scheduling batch jobs without considering dependencies, so downstream jobs run before upstream data is ready
  • -Letting batch job execution times grow unchecked until they exceed the available processing window
  • -Not alerting on batch job failures, so stale data goes undetected until someone manually checks

Pro Tips

  • +Use orchestration tools (Airflow, Dagster, Prefect) to manage batch job dependencies and scheduling
  • +Implement data freshness checks that verify batch job outputs before downstream systems consume them
  • +Build batch jobs to be idempotent - rerunning them should produce the same result without duplicating data
  • +Monitor batch job duration trends and optimize before jobs exceed their processing windows
