High-Throughput In-Memory Reconciliation System Design: State Machines, Snapshots, and WAL-Style Replay
For high-volume reconciliation workloads, an in-memory architecture replaces heavy SQL and heavyweight state frameworks with a model built on “memory as the state machine,” single-threaded sequential progression, and replayable file-based recovery. This approach significantly improves throughput while reducing engineering complexity. It addresses three core pain points: slow JOINs, fragmented state, and false positives across reconciliation … Read more
