Distributed Action Handler 25.4
Distributed Action Handler Help

# FastMirrorMode

Set to `true` to enable fast mirror mode. You can use this option only when MirrorMode is set to `true`.

You can use fast mirror mode to improve performance in cases where the Distributed Action Handler is used only for requesting information from child servers.

NOTE: When running the Distributed Action Handler in fast mirror mode:

- You must not send state-changing actions to the Distributed Action Handler. For example, the action parameters `Delete`, `State`, `StoreState`, and so on must not be used.

- Distributed Action Handler does not perform any extra processing on actions. For example, the action parameters Template, Output, and so on must not be used.

- You must not use action parameters using document IDs (for example, the `ID` parameter).

- You must not use distributed commands (actions that are sent to all child servers) and asynchronous actions.
