About:
CRoaring is a C library that implements Roaring Bitmaps, a compressed bitmap format that outperforms standard arrays and bitsets. It provides fast set operations like union, intersection, and difference while maintaining low memory usage. The library includes C++ bindings and is optimized for high-performance data processing.
|
Key Features:
- High-performance compressed bitmaps
- Fast set operations (union, intersection, difference)
- Memory-efficient storage
- C and C++ APIs
- Serialization support
|
Use Cases:
- Real-time analytics and data indexing
- Database query optimization
- In-memory data processing
- Large-scale data deduplication
|
Alternatives:
-
RoaringBitmap (Java)
– Java implementation of same format, CRoaring provides native C/C++ performance
-
bitset
– Standard bitsets use more memory for sparse data, Roaring compresses effectively
