Configuration

Camel.toml is the operator surface for rust-camel. CamelConfig deserializes the file into a profile-aware tree. Fields live under [default] and [<profile>] sections, deep-merged with includes and CAMEL_* overrides.

Top-level sections: [default.routes] (discovery globs), [components.*] (per-component defaults, untyped TOML), [supervision] (retry and backoff), [observability] (tracing and metrics), [idempotent_repo] (persistent idempotent backend).

Set CAMEL_PROFILE to select a profile. The [default] section always applies. The named profile merges on top. Use include = ["path/to/file.toml"] to pull shared sections from other files.

• Environment variable interpolation: substitute ${env:VAR} tokens in route files before parse
• Hot reload: swap pipelines at runtime without downtime
