It also discusses the levels of migration, which include the instrumentation layer and the collector layer. The author provides guidance on how to migrate to OpenTelemetry, including using an OpenTelemetry shim or complete re-instrumentation, and explains the impact of migrating from Jaeger to OpenTelemetry, such as improved tracer implementation and access to OpenTelemetry's framework plugins. Additionally, the post discusses the boundaries between Jaeger and OpenTelemetry, including the use of both collectors and the integration of Jaeger UI with OpenTelemetry. Finally, it recommends using PostgreSQL for long-term storage of metrics and traces, specifically with Promscale.
