@ -23,6 +23,12 @@ While events are purely gossip driven, remote execution relies on the KV store
|
|||
as a message broker. As a result, the `exec` command will not be able to
|
||||
properly function during a Consul outage.
|
||||
|
||||
**Verbose output warning:** use care to make sure that your command does not
|
||||
produce a large volume of output. Writes to the KV store for this output go
|
||||
through the Consul servers and the Raft consesnus algorithm, so having a large
|
||||
number of nodes in the cluster flow a large amount of data through the KV store
|
||||
could make the cluster unavailable.

## Usage
