이 가이드는 더블 텍스팅이 무엇인지에 대한 지식을 전제로 하며, 더블 텍스팅 개념 가이드에서 관련 내용을 학습할 수 있습니다. 이 가이드는 더블 텍스팅을 위한 interrupt 옵션을 다룹니다. 이 옵션은 이전 그래프 실행을 중단하고 더블 텍스트로 새로운 실행을 시작합니다. 이 옵션은 첫 번째 실행을 삭제하지 않고 데이터베이스에 유지하되 상태를 interrupted로 설정합니다. 아래는 interrupt 옵션을 사용하는 간단한 예제입니다.

​
설정

먼저 JS 및 CURL 모델 출력을 출력하기 위한 간단한 헬퍼 함수를 정의합니다 (Python을 사용하는 경우 이 단계를 건너뛸 수 있습니다): 
function prettyPrint(m) {
  const padded = " " + m['type'] + " ";
  const sepLen = Math.floor((80 - padded.length) / 2);
  const sep = "=".repeat(sepLen);
  const secondSep = sep + (padded.length % 2 ? "=" : "");

  console.log(`${sep}${padded}${secondSep}`);
  console.log("\n\n");
  console.log(m.content);
}
이제 필요한 패키지를 가져오고 클라이언트, 어시스턴트, 스레드를 인스턴스화하겠습니다. 
import asyncio

from langchain_core.messages import convert_to_messages
from langgraph_sdk import get_client

client = get_client(url=<DEPLOYMENT_URL>)
# Using the graph deployed with the name "agent"
assistant_id = "agent"
thread = await client.threads.create()

​
실행 생성

이제 두 개의 실행을 시작하고 두 번째 실행이 완료될 때까지 조인할 수 있습니다: 
# the first run will be interrupted
interrupted_run = await client.runs.create(
    thread["thread_id"],
    assistant_id,
    input={"messages": [{"role": "user", "content": "what's the weather in sf?"}]},
)
# sleep a bit to get partial outputs from the first run
await asyncio.sleep(2)
run = await client.runs.create(
    thread["thread_id"],
    assistant_id,
    input={"messages": [{"role": "user", "content": "what's the weather in nyc?"}]},
    multitask_strategy="interrupt",
)
# wait until the second run completes
await client.runs.join(thread["thread_id"], run["run_id"])

​
실행 결과 확인

스레드에 첫 번째 실행의 부분 데이터와 두 번째 실행의 데이터가 포함되어 있는 것을 확인할 수 있습니다. 
state = await client.threads.get_state(thread["thread_id"])

for m in convert_to_messages(state["values"]["messages"]):
    m.pretty_print()
출력:
