killAllSessionsByPattern

New in version 3.6.版本3.6中的新功能。

The killAllSessionsByPattern command kills all sessions that match any of the specified patterns. [1]

Syntax语法

The command has the following syntax:语法如下所示：

db.runCommand( { killAllSessionsByPattern: [ <pattern>, ... ] } )

The command takes an array of documents that specify the patterns to match:

PatternDescription描述
{ lsid: { id : <UUID> } } Specify the UUID portion of the session id to kill.
{ uid: <BinData> } Specifies the hash of the owner of the sessions to kill.
{ users: [ { user: <user>, db: <dbname> }, ... ] } Specifies the owners of the sessions to kill. Requires additional privileges. See Access Control.
{ roles: [ { role: <role>, db: <dbname> }, ... ] } Specifies the roles assigned to the owners of the sessions to kill. Requires additional privileges. See Access Control.

Specify an empty array to kill all sessions. [1]

To view existing sessions, see $listSessions operation or $listLocalSessions.

[1](1, 2) The killAllSessionsByPattern operation ignores sessions that have transactions in prepared state. See Behavior for details.

Behavior行为

In-progress Operations

Killing a session kills any in-progress operations in the session and closes any open cursors associated with these operations.

Killed Session Availability

The killed session may still be listed as a current session, and future operations may use the killed session. To view existing sessions, see $listSessions operation or $listLocalSessions.

Sessions with Transactions in Prepared State

The killAllSessionsByPattern 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.

Access Control

If the deployment enforces authentication/authorization, you must have the killAnySession to run the killAllSessionsByPattern command.

For patterns that include users or roles, you must also have privileges that grant impersonate action on the cluster resource.

Note

Users can kill their own sessions even without killAnySession privilege action.

Examples示例

Kill All Sessions for Specific Users

   { "uid" : BinData(0,"oBRA45vMY78p1tv6kChjQPTdYsnCHi/kA/fFMZTIV1o=") },
   { roles: [ { role: "readWrite", db: "test" } ] }
] } )
