file sink

The file sink configures Boundary to send events to a file.

sink {    name = "obs-sink"    description = "Observations sent to a file"    event_types = ["observation"]    format = "cloudevents-json"    file {      path = "/var/log/boundary"      file_name = "events.ndjson"    }  }

The sink stanza may be specified more than once to make Boundary send events to multiple sinks; however, each file sink must have a unique path + file_name.
