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
