-----------------------------------------
Summary: Add the ability to rollback any local transaction by
transaction ID
Key: IGNITE-23680
URL: https://issues.apache.org/jira/browse/IGNITE-23680
Project: Ignite
Issue Type: Improvement
Reporter: Pavel Pereslegin
In order to implement the SQL command
{code:sql}
KILL TRANSACTION txId
{code}
we need to add a new method to TxManager that will be able to rollback any
locally started (read-only and read-write) transaction by her ID.
For example
{code:java}
// returns false in case transaction not exists / was initiated on another node
/ already completed (or aborted)
boolean cancelLocal(UUID txId);
{code}
*NOTE:* It is assumed that the method will be called on all cluster nodes (via
a broadcast message). However, if it is possible to immediately and more
effectively implement a method for "global" transaction rollback in the entire
cluster, then it can be implemented immediately.
Something like
{code:java}
// returns false in case transaction not exists in cluster / already completed
(or aborted)
boolean cancelUUID txId);
{code}
