"The stabilisation includes the JSON schema for the data model, the YAML representation of configuration files, and the in-memory representation of configuration data."
"One of the biggest benefits of declarative configuration is the ability to define telemetry settings in configuration files rather than environment variables, giving a much richer language for specifying options."
"Getting all three observability signals configured in a single place has historically been a juggling act of environment variables, programmatic SDK initialisation code, and collector configs."
OpenTelemetry has stabilized key parts of its declarative configuration specification, which allows for vendor-neutral telemetry collection. The JSON schema, YAML configuration files, and in-memory data representation are now stable. Implementations are available in C++, Go, Java, JavaScript, and PHP, with ongoing work for .NET and Python. This configuration method enables users to define telemetry settings in files rather than environment variables, facilitating complex telemetry pipelines that can be version-controlled and shared across teams.
