redis and transactions | Mar 12, 2016 • Ding Jiao

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.


@array-reply: each element being the reply to each of the commands in the atomic transaction.

When using WATCH, EXEC can return a @nil-reply if the execution was aborted.
