EXECExecute every command queued since MULTI.
| Syntax | EXEC |
| Group | tx |
| Arity | 1 |
| Since | 1.0.0 |
| Flags | readonly, transaction |
| Complexity | O(sum of the queued commands' costs); with W watched keys, one extra O(W) pre-check fanned into O(min(W,S)) messages |
| Redis compatibility | differs: a MULTI batch spanning several shards is per-shard-atomic, not globally isolated (there is no cross-shard snapshot); a queue-time error aborts the whole batch with EXECABORT, but a runtime error inside EXEC leaves the other commands applied, as in Redis |
