วิธีใช้ Boto3 ตรวจสอบว่า Glue Job มีอยู่หรือไม่

ตัวอย่างโค้ด

ใช้โค้ดต่อไปนี้เพื่อตรวจสอบว่า Glue Job มีอยู่หรือไม่:

import boto3
from botocore.exceptions import ClientError

def check_glue_job_exists(job_name):
    session = boto3.session.Session()
    glue_client = session.client('glue')
    try:
        response = glue_client.get_job(JobName=job_name)
        return response
    except ClientError as e:
        raise Exception("boto3 client error in check_glue_job_exists: " + e.__str__())
    except Exception as e:
        raise Exception("Unexpected error in check_glue_job_exists: " + e.__str__())

# To check existing job
print(check_glue_job_exists("run_s3_file_job"))
# Job doesn't exist
print(check_glue_job_exists("run_s3_file_job_not_exist"))

ผลลัพธ์

# To check existing job
