Valkey RoaringRoaring Bitmaps for Valkey

Compressed bitmaps as native server types — 51 commands, 32/64-bit variants, and cross-language binary export. Runs on Valkey 8.1+ and Redis 7.4+.

Getting Started

What Is a Roaring Bitmap

Commands

📦

Cross-language binary export

R.EXPORT and R.IMPORT speak the CRoaring portable format — move bitmaps between Valkey and Java, Go, Python, C++, or Rust services without intermediate integer arrays.

🧮

Two value ranges

32-bit (R.*) and 64-bit (R64.*) command families with identical semantics, generated from a single generic implementation that cannot drift apart.

⚡

Fast set operations

AND, OR, XOR, NOT, ANDOR, DIFF, DIFF1 and ONE run on compressed containers — several times faster than native bitmaps on real datasets.

🔁

Valkey and Redis, stable replies

The same .so loads on both Valkey 8.1+ and Redis 7.4+, and command replies — argument grammar, error wording and reply types — are a stable contract, pinned byte for byte by the test suites.

💾

Persistence and replication

RDB snapshots, AOF with the default preamble configuration, verbatim replication to replicas, DUMP/RESTORE and COPY support.

🧪

Battle-tested

Unit and property tests, fuzzing and a 496-assertion integration suite on every push, plus a separate end-to-end suite validating the running server against real datasets and reference implementations.
