MGETReturn the values of multiple keys (cross-shard gather).
| Syntax | MGET key [key ...] |
| Group | string |
| Arity | -2 |
| Since | 1.0.0 |
| Flags | readonly |
| Complexity | O(N) keys, one O(1) probe each on the owning shard |
| Redis compatibility | differs: keys are grouped by shard and each shard is probed independently, so the reply is not a point-in-time snapshot across shards |
