Gufo Blob

Unified blob storage access with predictable semantics.

Documentation: https://docs.gufolabs.com/gufo_blob/

Source Code: https://github.com/gufolabs/gufo_blob/

Gufo Blob is a lightweight, typed abstraction layer for working with key-based object storage across different backends. It provides a consistent and predictable API for accessing, resolving, and iterating over data regardless of the underlying storage implementation.

Examples

Synchronous API

put/get/delete

from gufo.blob.sync import open_blob

with open_blob("/var/data") as blob:
    # Store
    blob.put("myproj/k1", b"data")
    # Get
    v = blob.get("myproj/k1")
    # Delete
    blob.delete("myproj/k1")

dict-like API

from gufo.blob.sync import open_blob

with open_blob("/var/data") as blob:
    # Save
    blob["myproj/k1"] = b"data"
    # Get
    v = blob["myproj/k1"]
    # Delete
    del blob["myproj/k1"]

Asynchronous API

from gufo.blob.aio import open_blob

async def main():
    async with open_blob("/var/data") as blob:
        # Store
        await blob.put("myproj/k1", b"data")
        # Get
        v = await blob.get("myproj/k1")
        # Delete
        await blob.delete("myproj/k1")

Features

• Sync and async modes - Provides API for both sync and async modes of operation.
• Unified blob abstraction — consistent API for working with different storage backends
• Backend-agnostic design — works with local filesystem and pluggable storage implementations
• Fully typed API — strict typing for keys, values, and storage contracts
• Agent-friendly architecture — explicit interfaces and uniform backend semantics simplify AI-assisted development
• Simple object model — intuitive Blob / BlobBase interface with predictable semantics
• Lazy operations — resources are initialized and opened only when required
• Explicit lifecycle control — optional open() / close() with context manager support
• Transparent connection handling — automatic resource management for connected backends
• Efficient scanning — fast iteration over stored keys with minimal overhead
• Key-based access model — uniform resolution of objects via string keys
• Error unification — all runtime issues reduce to BlobError and KeyError
• Deterministic behavior — consistent resolution and iteration order guarantees where applicable
• Extensible architecture — easy to add new storage backends and resolvers
• Designed for composition — works naturally inside larger systems and pipelines

On Gufo Stack

This product is a part of Gufo Stack - the collaborative effort led by Gufo Labs. Our goal is to create a robust and flexible set of tools to create network management software and automate routine administration tasks.

To do this, we extract the key technologies that have proven themselves in the NOC and bring them as separate packages. Then we work on API, performance tuning, documentation, and testing. The NOC uses the final result as the external dependencies.

Gufo Stack makes the NOC better, and this is our primary task. But other products can benefit from Gufo Stack too. So we believe that our effort will make the other network management products better.
