How to use Boto3 to get the details of all connection available in AWS Glue Data catalog?

Problem Statement − Use boto3 library in Python to get details of all connection present in AWS Glue Data catalog.

Example − Get the details of all connection definition.

Approach/Algorithm to solve this problem

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

Step 2 − There is no parameter.

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 − Call get_connections function.

Step 6 − It will fetch details of the connection definition from AWS Glue Data Catalog.

Step 7 − Handle the generic exception if something went wrong while checking the job.

Example

Use the following code to get definition of all connections in AWS Glue Data catalog −

import boto3
from botocore.exceptions import ClientError

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