Hyper-fast queue for Python

HyperQ

Hyper-fast queue for Python - A high-performance queue implementation using Cython and C++ for inter-process communication.

🚀 Features

• Lightning Fast: Optimized C++ implementation with Python bindings
• Inter-Process Communication: Shared memory-based queues for high-performance IPC
• Ring Buffer Architecture: Uses a ring buffer with double virtual memory mapping to the same physical memory.
• Two Queue Types:
  • HyperQ: General-purpose queue for Python objects
  • BytesHyperQ: Specialized queue for bytes data (even faster)
• Thread-Safe: Safe for concurrent access
• Unix-like Systems: Works on Linux and macOS (POSIX-compliant systems)
• Python 3.10+: Modern Python support

⚠️ Platform Support

Currently supported:

• ✅ Linux
• ✅ macOS

Not supported:

• ❌ Windows (uses POSIX-specific APIs)
• ❌ PyPy (uses POSIX-specific APIs and C++ extensions)

🔧 Technical Details

Ring Buffer Implementation

HyperQ uses a ring buffer with double virtual memory mapping to the same physical memory. This eliminates the need for 2 memcpy operations when data wraps around the buffer boundaries.

Shared Memory Architecture

• Header segment: Contains queue metadata, synchronization primitives, and buffer information
• Buffer segment: The actual data storage with double virtual memory mapping
• POSIX shared memory: Uses shm_open() and mmap() for cross-process memory sharing
• Synchronization: Uses POSIX mutexes and condition variables for thread/process safety

pip install -e .

Development Installation

git clone https://github.com/martinmkhitaryan/hyperq.git
cd hyperq
pip install -e ".[test]"

🎯 Quick Start

Basic Usage

import multiprocessing as mp
from hyperq import HyperQ, BytesHyperQ

# Create a queue with 1MB capacity
queue = HyperQ(1024 * 1024, name="/my_queue")

# Put data
queue.put("Hello, World!")
queue.put(42)
queue.put({"key": "value"})

# Get data
data = queue.get()  # "Hello, World!"
number = queue.get()  # 42
obj = queue.get()  # {"key": "value"}

Inter-Process Communication

import multiprocessing as mp
from hyperq import HyperQ

def producer(queue_name):
    queue = HyperQ(queue_name)
    for i in range(1000):
        queue.put(f"Message {i}")

def consumer(queue_name):
    queue = HyperQ(queue_name)
    for _ in range(1000):
        message = queue.get()
        print(f"Received: {message}")

if __name__ == "__main__":
    # Create queue in main process
    queue = HyperQ(1024 * 1024, name="/shared_queue")
    queue_name = queue.shm_name

    # Start producer and consumer processes
    p1 = mp.Process(target=producer, args=(queue_name,))
    p2 = mp.Process(target=consumer, args=(queue_name,))

    p1.start()
    p2.start()
    p1.join()
    p2.join()

Bytes-Specific Queue (Faster)

from hyperq import BytesHyperQ

# For bytes data, use BytesHyperQ for better performance
queue = BytesHyperQ(1024 * 1024, name="/bytes_queue")

# Put bytes data
queue.put(b"Hello, World!")
queue.put(b"Binary data")

# Get bytes data
data = queue.get()  # b"Hello, World!"

🔧 API Reference

HyperQ

class HyperQ:
    def __init__(self, capacity: int, name: str = None)

    def put(self, item) -> bool
    def get(self)  # Blocks until data is available
    def empty(self) -> bool
    def full(self) -> bool
    def size(self) -> int
    def clear(self)

BytesHyperQ

class BytesHyperQ:
    def __init__(self, capacity: int, name: str = None)

    def put(self, data: bytes) -> bool
    def get(self) -> bytes  # Blocks until data is available
    def empty(self) -> bool
    def full(self) -> bool
    def size(self) -> int
    def clear(self)

Parameters

• capacity: Maximum size of the queue in bytes
• name: Optional name for the shared memory segment (max 28 characters)

Important Notes

• Blocking operations: get() blocks indefinitely until data is available
• No timeout support: Currently no timeout functionality is implemented
• Queue names: Must be 28 characters or less
• Platform limitation: Only works on Unix-like systems (Linux/macOS)
