redisZSET score precision for nanosecond timestamps
Redis Sorted Sets (ZSETs) are frequently used for time-series indexing by storing Unix timestamps as scores. This allows for efficient range queries using ZRANGEBYSCORE . However, Redis stores scores as double-precision floating-point numbers. When implementing high-resolution telemetry, there is a concern regarding the precision limit of these floating-poin
