AI Dev Tool: OpenTelemetry Span Exporter & Tail-Based Sampler for FastAPI

1. The Production Bottleneck

We engineered this zero-bloat Python 3.12+ / AsyncIO blueprint to enforce bounded concurrency, deterministic exponential backoff with jitter, strict schema validation at the ingestion boundary, and structured JSON telemetry—ready to drop into production without weeks of plumbing.

AI Dev Tool: OpenTelemetry Span Exporter & Tail-Based Sampler for FastAPI

This module provides a production-ready implementation of an OpenTelemetry span exporter and tail-based sampler for FastAPI applications.
It utilizes a bounded concurrency model to ensure efficient and reliable operation.

The module can be used as a CLI tool to benchmark and self-test the span exporter and sampler.
To use the CLI, simply run the module with the following command:
    python -m ai_dev_tool --help

The CLI provides the following options:
    --span-exporter-url: The URL of the span exporter (default: http://localhost:55678/v1/traces)
    --tail-based-sampler: Enable or disable the tail-based sampler (default: True)
    --max-concurrency: The maximum number of concurrent requests (default: 10)
    --benchmark-duration: The duration of the benchmark in seconds (default: 10)

Example usage:
    python -m ai_dev_tool --span-exporter-url http://localhost:55678/v1/traces --tail-based-sampler --max-concurrency 10 --benchmark-duration 10
