How to handle DB I/O contention and single-thread bottlenecks in high-volume settlement batches?
Hi everyone,
I’ve been diving deep into the onca study regarding system scalability lately, especially when dealing with massive settlement traffic at the end of the month.
We’ve hit a wall where single-batch process capabilities are being exceeded, causing significant DB lock contention. This ripple effect eventually paralyzes our real-time API responses—definitely not a situation you want to be in.
The structural limits of sequential processing are becoming clear: even with enough system resources, a delay in one segment halts the entire pipeline. Based on some recent architectural shifts, we are looking at:
- Partitioning settlement targets into chunks and distributing them across worker nodes (Parallel Processing).
- Utilizing Read Replicas specifically for batch processing to offload the main database.
However, the real challenge lies in the implementation details. For those of you running similar parallel architectures: How are you currently designing your Distributed Lock management and data consistency logic to prevent double-counting across nodes?
I'd love to hear your experiences or any pitfalls we should avoid.
Cheers!
