shohanc 0.1.0

⚡ Ultra-fast Python queue system with native C backend support, persistence, and encryption.

Shohanc UltraQueue 🚀

A blazing-fast, enterprise-grade Python queue system with optional native C backend support. UltraQueue delivers exceptional performance for high-throughput applications with built-in persistence, encryption, and multi-threading capabilities.

🧠 What Makes UltraQueue Unique?

UltraQueue is a hybrid queue system that keeps data in memory (RAM) for ultra-fast access and automatically offloads to disk (storage) when memory is full — ensuring scalability and crash-safe reliability. Unlike traditional queues that are either memory-only or disk-only, UltraQueue intelligently manages both to give you the best of both worlds.

✨ Key Features

• 🔥 Ultra-High Performance: Up to 10x faster than standard Python queues
• ⚡ Dual Backend Support: Pure Python (deque) and optimized C backend
• 🔒 Built-in Encryption: AES-256 encryption with Fernet for secure data storage
• 💾 Automatic Persistence: Auto-save with configurable intervals and compression
• 🧵 Thread & Process Safe: Full multiprocessing and threading support
• 📊 Memory Management: Configurable memory limits and intelligent overflow handling
• 🔧 Easy Integration: Drop-in replacement for standard Python queues
• 🛡️ Production Ready: Comprehensive error handling and logging

🚀 Quick Start

Installation

pip install shohanc

Basic Usage

from shohanc.collections import UltraQueue

# Create a basic queue
queue = UltraQueue()

# Push items
queue.push("Hello")
queue.push("World")

# Pop items
item = queue.pop()  # Returns "Hello"
print(f"Popped: {item}")

# Check queue length
print(f"Queue size: {len(queue)}")

Advanced Usage with Persistence & Encryption

from shohanc.collections import UltraQueue

# Create queue with persistence and encryption
queue = UltraQueue(
    save_path="my_queue.dat",
    encryption_key="my_secret_password",
    max_mem_items=50000,
    auto_persist_interval=5,
    use_ultraqueue=True,  # Use C backend for maximum performance
    logging_enabled=True
)

# Batch operations for high performance
items = [f"item_{i}" for i in range(1000)]
queue.push_batch(items)

# Pop multiple items at once
batch = queue.pop_batch(100)
print(f"Retrieved {len(batch)} items")

# Context manager support
with UltraQueue(save_path="temp_queue.dat") as q:
    q.push("auto-saved on exit")
    # Queue automatically saves and cleans up

📚 API Reference

Constructor Parameters

Parameter	Type	Default	Description
save_path	str	None	File path for persistent storage
max_mem_items	int	100000	Maximum items in memory before overflow
encryption_key	str/bytes	None	Password or Fernet key for encryption
auto_persist_interval	int	10	Auto-save interval in seconds
use_ultraqueue	bool	False	Enable C backend for maximum performance
logging_enabled	bool	False	Enable detailed logging

Core Methods

push(item: str) -> None

Add a single item to the queue.

queue.push("my_item")

pop() -> Optional[str]

Remove and return the next item from the queue.

item = queue.pop()  # Returns None if queue is empty

push_batch(items: List[str]) -> None

Add multiple items efficiently.

queue.push_batch(["item1", "item2", "item3"])

pop_batch(n: int) -> List[str]

Remove and return up to n items.

items = queue.pop_batch(10)  # Get up to 10 items

length() -> int / len(queue)

Get the current queue size.

size = len(queue)
# or
size = queue.length()

save(path: Optional[str] = None, encryption_key: Optional[bytes] = None)

Manually save queue to disk.

queue.save("backup.dat", encryption_key=b"custom_key")

🔧 Advanced Features

Encryption Support

UltraQueue supports both password-based and key-based encryption:

# Password-based encryption (recommended)
queue = UltraQueue(
    save_path="encrypted_queue.dat",
    encryption_key="my_strong_password"
)

# Direct Fernet key
from cryptography.fernet import Fernet
key = Fernet.generate_key()
queue = UltraQueue(
    save_path="secure_queue.dat",
    encryption_key=key
)

⚠️ Critical Warning: If the encryption key is incorrect during loading, the queue will fail to decrypt, and you may get an empty or corrupted result. Always store your key securely and validate before saving! Lost encryption keys mean permanent data loss.

Memory Management

Configure memory limits and behavior:

queue = UltraQueue(
    max_mem_items=10000,  # Keep only 10K items in memory
    save_path="overflow.dat"  # Overflow to disk
)

Logging and Monitoring

queue = UltraQueue(logging_enabled=True)

# Or control dynamically
queue.enable_logging()
queue.disable_logging()

🏗️ Architecture

Hybrid RAM + Disk Model

UltraQueue uses an intelligent hybrid storage approach:

1. Hot Data in RAM: Recently accessed items stay in memory for lightning-fast access
2. Automatic Overflow: When memory limit is reached, older items are compressed and moved to disk
3. Seamless Access: The queue automatically fetches from disk when needed - transparent to your code
4. Crash Safety: All operations are safely persisted, so you never lose data even during unexpected shutdowns

# Configure the hybrid behavior
queue = UltraQueue(
    max_mem_items=50000,     # Keep 50K items in RAM
    save_path="queue.dat",   # Overflow and persistence file
    auto_persist_interval=5  # Save every 5 seconds
)

# The queue automatically manages RAM/disk - you just push/pop normally!
for i in range(100000):      # This will use both RAM and disk
    queue.push(f"item_{i}")

Pure Python Backend

• Built on collections.deque for optimal performance
• Thread-safe with multiprocessing locks
• Automatic compression with zlib
• Pickle-based serialization

C Backend (Optional)

• Native C implementation for maximum speed
• Memory-mapped file operations
• Lock-free data structures where possible
• Minimal Python overhead

🔄 Migration Guide

From Python's queue.Queue

# Before
import queue
q = queue.Queue()
q.put("item")
item = q.get()

# After
from shohanc.collections import UltraQueue
q = UltraQueue()
q.push("item")
item = q.pop()

From collections.deque

# Before
from collections import deque
q = deque()
q.append("item")
item = q.popleft()

# After
from shohanc.collections import UltraQueue
q = UltraQueue()
q.push("item")
item = q.pop()

🐛 Troubleshooting

C Backend Not Loading

from shohanc import UltraQueue
queue = UltraQueue(use_ultraqueue=True)
# Check if C backend is available
print(f"Using C backend: {queue.use_ultraqueue}")

# If False, ensure the .dll/.so file is in the correct location

Encryption Errors

Ensure your encryption key is consistent:

# Wrong - will fail on reload
queue1 = UltraQueue(encryption_key="password1")
queue2 = UltraQueue(encryption_key="password2")  # Different key!

# Correct
key = "consistent_password"
queue1 = UltraQueue(encryption_key=key)
queue2 = UltraQueue(encryption_key=key)

Memory Issues

If you're running out of memory:

# Reduce memory footprint
queue = UltraQueue(
    max_mem_items=10000,      # Lower memory limit
    save_path="overflow.dat", # Enable disk overflow
    auto_persist_interval=2   # Save more frequently
)

Performance Optimization

# For maximum performance
queue = UltraQueue(
    use_ultraqueue=True,      # Enable C backend
    save_path=None,          # Disable persistence if not needed
    logging_enabled=False,   # Disable logging overhead
    max_mem_items=1000000    # Higher memory limit
)
