Current mirroring feature supports mirror data from remote to home. In certain scenario such as building distributed coordination control plane (such as IOT, AI Agents), it would be handy to support mirroring from home to remote. This allow home to push out application level commands or requests to remote(edge) devices.

In the mirror topic creation, new flag --home-to-remote would be added to mark that mirrored topic would be used for mirroring from home to remote cluster.

If this flag is supplied, then following produce policy would be applied.

• producing to topic from remote would be prohibited.
• producing to topic from home would be allowed.

Without this flag, existing produce policy would be applied.

Flag can be applied like this:

$ fluvio topic create edge-request --mirror  --home-to-remote

or with mirror configuration:

$ fluvio topic create edge-request --mirror-apply mirror.json --home-to-remote
