Maximum capacity in bytes (0 = unlimited)

used: u64

Current used bytes

cost_per_gb: f64

Cost per GB per month (for cost-aware routing)

avg_latency_ms: f64

Average read latency in milliseconds

size_threshold: Option<u64>

Block size threshold (route blocks larger than this)

healthy: bool

Whether this backend is healthy

read_enabled: bool

Whether to use for reads

write_enabled: bool

Whether to use for writes
