pilotctl --json publish "$PEER" datasets --data '{"type":"dataset_available","name":"sales_data","format":"csv","rows":1000}'

Request Dataset

pilotctl --json send-message "$DEST" --data '{"type":"dataset_request","name":"sales_data","preferred_format":"json"}'

Send Dataset with Metadata

pilotctl --json send-message "$DEST" --data '{"type":"dataset_metadata","name":"sales_data","schema":{"columns":["date","amount"]}}'

Workflow Example

#!/bin/bash
# Dataset exchange

PEER="agent-b"

publish_dataset() {
  local file="$1"
  local name="${2:-$(basename $file .csv)}"
  local rows=$(wc -l < "$file")

  pilotctl --json publish "$PEER" datasets \
    --data "{\"type\":\"dataset_available\",\"name\":\"$name\",\"format\":\"csv\",\"rows\":$rows}"
}

request_dataset() {
  local name="$1"
  local publisher="$2"

  pilotctl --json send-message "$publisher" \
    --data "{\"type\":\"dataset_request\",\"name\":\"$name\",\"preferred_format\":\"csv\"}"

  sleep 2
  pilotctl --json received
}
