OpenTelemetry & Distributed Tracing: A Jaeger v2 Deep Dive
summary
Explains that Jaeger v2 is rebuilt natively on OpenTelemetry and shows a working demo (Hot Rod and Astronomy Shop) with live traces, a topology view, and a critical path heatline that pinpoints a SQL lock causing a 1+ second delay. Describes storage options (Cassandra, OpenSearch/Elasticsearch, soon ClickHouse), Kafka queuing for bursts, and an embedded collector extension model plus a single-binary config for Jaeger v2 that supports head-, tail- and adaptive sampling.
