🚀

Performance

Up to 8x faster than Redis native bitmaps for O(N) operations while maintaining O(1) performance for single-bit operations.

💾

Memory Efficient

Adaptive compression automatically chooses optimal storage format, often reducing memory usage by 2-10x compared to uncompressed bitmaps

🔧

Drop-in Replacement

Familiar Redis-style commands that seamlessly integrate with your existing Redis workflow and applications

⚡

Smart Compression

Automatically switches between array, bitmap, and run-length encoding based on data density for optimal performance

🛠️

Production Ready

Built on the battle-tested CRoaring library with comprehensive test coverage and proven reliability in production environments

📊

Analytics Optimized

Perfect for user analytics, segmentation, real-time filtering, and any application requiring fast set operations on large datasets

Why Redis Roaring? ​

Traditional Redis bitmaps work great for dense data but can be memory-intensive and slow for sparse datasets. Redis Roaring combines the familiar Redis bitmap interface with the power of Roaring Bitmaps, giving you the best of both worlds.

The Problem with Traditional Bitmaps ​

bash
# Traditional Redis bitmap for user IDs 1, 1000000
SETBIT users:active 1 1
SETBIT users:active 1000000 1
# Result: ~256KB allocated for just 2 records!

The Redis Roaring Solution ​

bash
# Redis Roaring bitmap for the same data
R.SETBIT users:active 1 1
R.SETBIT users:active 1000000 1
# Result: ~13 bytes allocated

This project leverages the industry-standard CRoaring library, which powers bitmap operations
