Description

Compressed bitmap indexes can be stored and processed efficiently in C or C++ using SIMD-optimized roaring bitmaps. It is useful for developers building analytics, search, database, or high-volume set-operation systems.

This is a development library. Validate data compatibility, CPU feature use, and performance under the workloads your application actually runs.
