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 implements an OpenTelemetry span exporter and tail-based sampler for FastAPI.
It utilizes bounded concurrency to ensure efficient and reliable operation.
The module can be run from the command line, accepting configuration options as arguments.
Usage:
python -m ai_dev_tool [options]
Options:
--config-file PATH Path to configuration file (default: config.json)
--exporter-endpoint URL OpenTelemetry exporter endpoint (default: http://localhost:55678/v1/traces)
--sampler-config PATH Path to sampler configuration file (default: sampler_config.json)
--concurrency-limit INT Maximum number of concurrent requests (default: 10)
--log-level STR Logging level (default: INFO)
Architecture:
The module consists of the following components:
1. OpenTelemetry Span Exporter: responsible for exporting spans to the OpenTelemetry collector.
2. Tail-Based Sampler: responsible for sampling spans based on a tail-based sampling strategy.
3. FastAPI Integration: integrates the span exporter and sampler with FastAPI.
Bounded Concurrency:
The module uses bounded concurrency to ensure efficient and⚡ Instant browser download upon Stripe redirect • 🛡️ Permissive MIT Commercial License
