OxiMem, OxiDB's in-memory engine, now speaks PFADD, PFCOUNT and PFMERGE. How HyperLogLog works in detail, OxiMem's ASCII encoding and what it costs, the speedups, and side-by-side measurements against Redis 8.6.1: identical estimates, 3 to 5 times faster multi-key counts, and Redis level or ahead on single-key work.

I built a RESP-speaking key-value layer into OxiDB: five data types, TTLs, pub/sub, WATCH, Lua and snapshots. Real redis-cli and redis-py sessions, benchmarks against Redis 8.6, and the honest limits.
