How Simple Logic Helped a Leading Bank Cut Downtime and Boost Performance with MySQL Range Partitioning

Client Overview

A prominent bank with a large customer base and high transaction volumes was facing performance issues and frequent downtime. Their legacy database setup couldn’t keep up with the growing demand, especially during peak hours. They needed a solution that would not only improve speed but also ensure reliability and scalability.

The Challenge

• Slow Transactions: Queries on large tables were taking too long, affecting customer experience.
• Frequent Downtime: Maintenance windows disrupted operations and led to SLA violations.
• Scalability Limits: The system couldn’t handle increasing data volumes efficiently.
• Compliance Risks: Downtime and delays threatened regulatory compliance.

Our Approach

Simple Logic stepped in with a clear goal: optimize performance and reduce downtime using MySQL range partitioning and advanced tuning techniques.

🔹 Step 1: Database Audit

We analyzed the client’s existing schema, query logs, and performance metrics to identify bottlenecks.

🔹 Step 2: Range Partitioning

We implemented MySQL range partitioning on high-volume tables, segmenting data by transaction date and account type. This allowed the system to target only relevant partitions, drastically improving query speed.

🔹 Step 3: Performance Tuning

We fine-tuned MySQL parameters such as:

• innodb_buffer_pool_size
• query_cache_size
• tmp_table_size
• Indexing strategies

🔹 Step 4: Downtime Mitigation

Using tools like pt-online-schema-change, we enabled schema updates without locking tables—ensuring zero downtime during maintenance.

The Results

Client Impact

• Faster Banking Operations: Customers experienced quicker transactions and fewer delays.
• Improved Reliability: Near-zero downtime improved trust and compliance.
• Scalable Infrastructure: Ready to support future growth and digital transformation.
• Cost Savings: Reduced overhead from maintenance and support.
