Lightning Talk: Weaving Legacy and OpenTelemetry: A Schema Strategy With Weaver
summary
Comcast describes a migration that uses Weaver to merge OpenTelemetry semantic conventions with an injected legacy namespace, producing Elasticsearch JSON schema plus YAML and Markdown outputs via Jinja templates. The pipeline filters deprecated attributes, maps semantic types to backend types, enforces attribute uniqueness in templates, and supports gradual adoption across 3,000+ microservices, preserving existing queries and visualizations while reducing migration friction.
