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.
