Write-Heavy Workload: Why a Custom Database Engine Fits

When writes dominate (event streams, logs, metrics, audit trails), generic SQL or even many NoSQL stores can become the bottleneck. A custom engine tuned for append and bulk read can fix that.

Read-heavy workloads can lean on caches and indexes. Write-heavy systems need: minimal lock contention, append-friendly storage, efficient compaction and retention, and optional batching. Off-the-shelf DBs often optimize for mixed read/write, so you pay in CPU and I/O for features you don’t need on the hot path.

• •Append-only or log-structured storage – No in-place updates; writes are sequential. Higher throughput and predictable latency.
• •Batching and compression – Writes grouped and compressed before flush. Fewer I/O ops and smaller storage.
• •Retention and compaction – Built-in policies for how long to keep data and how to merge/delete. No fighting the DB’s generic model.
