How to use Boto3 to get the workflows that are created in your account?

Boto3PythonServer Side ProgrammingProgramming

Approach/Algorithm to solve this problem

Step 1 − Import boto3 and botocore exceptions to handle exceptions.

Step 2 − No parameter is required for this function. It will fetch all listed triggers for user account and then display metadata of each triggers.

Step 3 − Create an AWS session using boto3 library. Make sure region_name is mentioned in default profile. If it is not mentioned, then explicitly pass the region_name while creating the session.

Step 4 − Create an AWS client for glue.

Step 5 − Now use list_workflows function to get all jobs those are listed in user account.

Step 6 − Call batch_get_workflows and pass the job names fetched in previous function.

Step 7 − It returns list_of_workflows and metadata of each workflows.

Step 8 − Handle the generic exception if something went wrong while checking the job.

Example

Use the following code to fetch the details of each workflow created in the user account −

import boto3
from botocore.exceptions import ClientError

def get_resource_maetadata_of_workflows():
   session = boto3.session.Session()
   glue_client = session.client('glue')
   try:
      list_of_workflows = glue_client.list_workflows()
      response = glue_client.batch_get_workflows( Names=list_of_workflows['Workflows'])

      return list_of_workflows, response
   except ClientError as e:
      raise Exception( "boto3 client error in get_resource_maetadata_of_workflows: " + e.__str__())
   except Exception as e:
      raise Exception( "Unexpected error in get_resource_maetadata_of_workflows: " + e.__str__())

a, b = get_resource_maetadata_of_workflows()
#List of Workflows
print(a)
#Resource metadata of each Workflow
print(b)

Output
