TRANSACTION KILL

Cancels an open transaction of this member.

Syntax

TRANSACTION KILL id

Argument	Type	Description
id	integer	Transaction id as listed by TRANSACTION LIST

Return Value

Simple string: OK on success.

Behavior

The command cancels the transaction with the given id on this member only. Use TRANSACTION LIST to find the id.

The transaction is not closed. It stays in the TRANSACTION LIST output until its session runs ROLLBACK. That session gets a TRANSACTION_CANCELLED error on its next read or on COMMIT. A write alone does not fail, because writes wait on the client until commit. An auto-commit transaction is closed when its command fails.

Transactions with client_id -1 belong to the member itself. They cannot be killed.

Errors

Transaction errors:

Error Code	Error message	Cause
TRANSACTION	no such transaction: <id>	No open transaction has this id
TRANSACTION	internal transactions cannot be killed	The transaction belongs to the member itself

Examples

Kill the transaction of another session:

> TRANSACTION KILL 42
OK

The owner session then sees:

> ZGET key
(error) TRANSACTION_CANCELLED Operation aborted because the transaction was cancelled

> ROLLBACK
OK
