EXEC [ IFEQ key value | IFNE key value | NX nonexisting-key | XX existing-key ] [ [ IFEQ key value | IFNE key value | NX nonexisting-key | XX existing-key ] ... ]
Complexity:
O(N) for N conditions, plus the complexity of commands in the transaction
Since:
1.2.0

@slow, @transaction

Executes all previously queued commands in a transaction and restores the connection state to normal.

When using WATCH, EXEC will execute commands only if the watched keys were not modified, allowing for a check-and-set mechanism.
