行为
会话识别
MongoDB concatenates each of the specified UUIDs with the hash of the authenticated user credentials to identify the user's sessions to kill. If the user has no session that match, the killSessions has no effect.
进行中的操作
终止会话会终止会话中所有进行中的操作，并关闭与这些操作关联的所有打开的游标。
终止会话可用性
被终止的会话可能仍会列为当前会话，并且将来的操作可能会使用被终止的会话。 要查看现有会话，请参阅$listSessions操作或$listLocalSessions 。
事务处于准备状态的会话
The killSessions operation ignores sessions that have Transactions in prepared state. Transactions in prepared state refer to transactions with write operations that span multiple shards whose commit coordinator has completed the "sendingPrepare" action.
