ENSURING RELIABLE OPENTELEMETRY INGESTION AT SCALE

Summary from the TLDR IT newsletter

ClickHouse describes how its LogHouse observability platform evolved to handle OpenTelemetry ingestion at 50 million events per second without losing telemetry during ClickHouse backpressure. After finding in-memory queues and local collector write-ahead logs inadequate, the company designed a priority-based failover pipeline that keeps ClickHouse in the hot path and uses blob storage as a durable overflow buffer.
