Complexity

INFO / NODES / SLOTS / SHARDS / MYID: O(S). KEYSLOT: O(len(key)). COUNTKEYSINSLOT: O(N/S)

Complexity and compatibility are read out of kevy's implementation, not copied from Redis's reference. Several genuinely differ.

Redis compatibility

Differs

a read-only virtual-node topology derived from config (one virtual master per shard) — no gossip, no MEET / FORGET / SETSLOT effect (they reply OK as no-ops), no MIGRATE / ASK, no failover; COUNTKEYSINSLOT counts only the answering shard's keys
