Chunking Strategies for Tabular Data Sources
July 1, 2025 By Yodaplus
Tabular data, organized in rows and columns, remains central to many business systems such as financial dashboards, ERP tools, supply chain reports, and retail analytics. As data volumes grow and business needs become more complex, handling this information efficiently can be challenging. This is where chunking becomes useful.
Chunking is the process of splitting large datasets into smaller, manageable parts. It is a practical method widely used in artificial intelligence applications across FinTech, retail, and supply chain systems to improve performance and scalability.
In this blog, we’ll explore what chunking is, why it matters, and how to use it effectively to get more value from your tabular data.
Why Chunking Matters
As organizations expand their analytics and AI capabilities, tabular data sources such as transaction logs and inventory records are growing rapidly in size. Chunking offers a practical way to manage this growth by improving how data is processed and analyzed.:
- Improve memory efficiency by processing data in parts
- Speed up computations and reduce processing time
- Enable real-time or near real-time data streaming
- Support parallel processing for AI or ML models
- Maintain responsiveness in dashboards and reporting tools
These benefits are particularly important in Financial Technology Solutions and Enterprise Resource Planning (ERP) systems, where reliability and speed are non-negotiable.
1. Fixed Row-Size Chunking
This strategy splits the dataset into uniform blocks based on a fixed number of rows (e.g., 10,000 rows per chunk).
Best for:
- Pagination in web applications
- Batch processing in ERP reporting
- Uniform datasets in retail technology solutions
Supported by:
- SQL queries with LIMIT and OFFSET
- Python tools like Pandas (chunksize)
- Data pipelines in Airflow or NiFi
2. Time-Based Chunking
Time-based chunking divides data into intervals like daily, weekly, or monthly, based on a timestamp field. It’s ideal for supply chain technology and FinTech solutions that require time-series insights.
Use cases:
- Inventory flow analysis by day
- Payment processing logs
- Historical demand prediction for retailers
Best practice: Index the timestamp field and apply filters to avoid full-table scans.
3. Key-Based Chunking
This involves chunking data based on unique keys such as customer IDs, product categories, or regions. It ensures that related data stays grouped, which is essential for personalized analytics or regional reporting.
Relevant to:
- Artificial Intelligence solutions for customer segmentation
- Retail technology solutions for geo-targeted promotions
- FinTech customer risk profiling
Using hash functions or group-by logic, key-based chunking improves both model accuracy and explainability.
4. Dynamic Chunking Based on System Resources
Rather than a fixed size, chunk size adapts based on available system memory or CPU load. This is helpful in real-time or resource-constrained environments.
When to use:
- Cloud-native AI systems with auto-scaling
- Mobile or edge deployments
- Continuous integration of financial technology solutions
Dynamic chunking is supported by platforms like Apache Spark, Dask, and Python generators.
5. Semantic or Contextual Chunking
This strategy breaks data based on its business meaning—fiscal quarters, promotional cycles, or product life stages.
Ideal for:
- Interpretable AI-powered reporting
- Strategic decision-making in enterprise resource planning
- Compliance monitoring in FinTech solutions
While more complex to implement, semantic chunking adds valuable context that improves model insights and business understanding.
Best Practices
To get the most out of your chunking strategy, keep these best practices in mind:
- Index before chunking for faster filtering
- Combine with caching to optimize repeated access
- Use parallelism for large-scale analytics workloads
- Preserve data integrity, especially for event-based logs
- Log checkpoints for resumable batch processing
Chunking in Action: Use Case Examples
- In Supply Chain Technology:
Chunking historical inventory data by week helps AI models predict stockouts while keeping training cycles short and interpretable. - In FinTech Solutions:
When processing millions of transactions for fraud detection, chunking by time and customer segment allows parallel risk scoring without overwhelming the system. - In Retail Technology Solutions:
Daily sales data can be chunked by store or region, enabling quicker BI dashboard refreshes and faster promotional performance analysis.
