EXEC

Syntax​

EXEC

Time complexity: Depends on commands in the 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.

Return​

Array reply: each element being the reply to each of the commands in the atomic transaction.

When using WATCH, EXEC can return a Null reply if the execution was aborted.
