Azure Functions DB

Unified DB integration (trigger + input/output binding) for Azure Functions Python v2.

Features

• DB Change Detection (Trigger): Poll-based pseudo trigger that detects new/changed rows via cursor tracking
• Input Binding: Read rows declaratively with @db.input() — data injected into your handler
• Output Binding: Write rows declaratively with @db.output() and DbOut.set()
• Client Injection: Full imperative control with @db.inject_reader() / @db.inject_writer()
• Multi-DB Support: PostgreSQL, MySQL, SQL Server via SQLAlchemy
• Azure Functions v2 Native: Integrates with the Python v2 programming model

Quick Start

pip install azure-functions-db[postgres]

from azure_functions_db import DbBindings, DbOut, DbReader, DbWriter
from azure_functions_db import SqlAlchemySource, BlobCheckpointStore, EngineProvider

Docs ownership & canonical sources

This project maintains two complementary documentation sets:

• Numbered specs & ADRs (00-* … 28-*, including the ADRs) are the canonical source for design and API contract. 04-python-api-spec.md is the authoritative API reference; the auto-generated API Reference is derived from source and cross-links back to it.
• Standard user-facing pages (this index, Installation, Getting Started, Troubleshooting, FAQ) are derivations tuned for task-oriented reading.

When changing behavior, update 04-python-api-spec.md first, then propagate to the user-facing pages so the two systems do not drift.
