uv add py-key-value-aio
poetry add py-key-value-aio

## Description

# Python Key-Value Libraries

This monorepo contains:

- `py-key-value-aio`: Async key-value store library (primary and supported).
- `py-key-value-sync`: Sync version (no longer planned; async-only focus).

## Documentation

- [Full Documentation](https://strawgate.com/py-key-value/)
- [Getting Started Guide](https://strawgate.com/py-key-value/getting-started/)
- [Stores Guide](https://strawgate.com/py-key-value/stores/)
- [Wrappers Guide](https://strawgate.com/py-key-value/wrappers/)
- [Adapters Guide](https://strawgate.com/py-key-value/adapters/)
- [API Reference](https://strawgate.com/py-key-value/api/protocols/)

## Why use this library?

- **Multiple backends**: Aerospike, Azure Tables, chDB, DuckDB, DynamoDB,
  Elasticsearch, FileTree, Firestore, Keyring, Memcached, MongoDB, OpenSearch,
  PostgreSQL, Redis, RocksDB, S3, Valkey, Vault, Windows Registry, and
  In-memory, Disk, etc.
- **TTL support**: Automatic expiration handling across all store types
- **Type-safe**: Full type hints with Protocol-based interfaces
- **Adapters**: Pydantic model support, raise-on-missing behavior, etc
- **Wrappers**: Statistics tracking and extensible wrapper system
- **Collection-based**:...

## AI interpretation — verify before relying

An async-only key-value store library providing a pluggable Protocol-based interface to multiple backends (Redis, DynamoDB, MongoDB, in-memory, disk, and others) with TTL support and type-safe operations.

Verdict: A well-maintained, actively developed async key-value abstraction with low install friction and no known vulnerabilities. Best suited for framework authors seeking a backend-agnostic storage protocol; end users should be aware it is async-only, stores wrapped entries (not raw values), and uses runtime type checking via beartype.
