Struct RedisMemoryProfile 

pub struct RedisMemoryProfile {
    pub used_bytes: u64,
    pub max_bytes: u64,
    pub last_updated: Instant,
    pub pending_writes_estimate: u64,
}

Cached Redis memory profile to avoid round-trips.

Fields

used_bytes: u64

Used memory in bytes (from INFO MEMORY)

max_bytes: u64

Max memory in bytes (from CONFIG GET maxmemory)

last_updated: Instant

When we last refreshed from Redis

pending_writes_estimate: u64

Estimated bytes written since last refresh
