We engineered this zero-bloat Cloudflare Workers / TypeScript 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: PostgreSQL pgvector Hybrid BM25 + Cosine Reranker Pipeline.
This module implements a hybrid BM25 and cosine reranker pipeline for PostgreSQL pgvector.
It utilizes bounded concurrency to ensure efficient and reliable processing of large datasets.
The module can be used as a command-line tool, providing options for configuring the pipeline and logging.
Usage:
python -m ai_dev_tool --host <host> --database <database> --user <user> --password <password> --query <query> --k <k>
Architecture:
1. Initialize the PostgreSQL connection and pgvector extension.
2. Define the hybrid BM25 and cosine reranker pipeline.
3. Process the query using the pipeline, utilizing bounded concurrency.
4. Log the results and any errors that occur.
Bounded Concurrency:
The module uses a bounded concurrency approach to ensure efficient and reliable processing of large datasets.
This is achieved through the use of a thread pool with a limited number of worker threads.
CLI Usage:
The module can be used as a command-line tool, providing options for configuring the pipeline and logging.
The available options are:
--host: The host name or IP address of the PostgreSQL server
