How to use Boto3 to get the details of multiple triggers at a time?
Problem Statement − Use boto3 library in Python to get the triggers that are available in your account. For example, get the details of triggers that are allowed in your account.
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 the listed triggers for the user account and then display the metadata of each triggers.
Step 3 − Create an AWS session using boto3 library. Make sure the region_name is mentioned in the 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_triggers function to get all jobs those are listed in user account.
Step 6 − Call batch_get_triggers and pass the job names fetched in previous function.
Step 7 − It returns list_of_triggers and metadata of each triggers.
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 triggers listed in user account −
import boto3
from botocore.exceptions import ClientError
def get_resource_maetadata_of_triggers():
session = boto3.session.Session()
glue_client = session.client('glue')
try:
list_of_triggers = glue_client.list_triggers()
response = glue_client.batch_get_triggers(TriggerNames=list_of_triggers['TriggerNames'])
return list_of_triggers, response
except ClientError as e:
raise Exception( "boto3 client error in get_resource_maetadata_of_triggers: " + e.__str__())
except Exception as e:
raise Exception( "Unexpected error in get_resource_maetadata_of_triggers: " + e.__str__())
a, b = get_resource_metadat_of_triggers()
#List of Triggers
print(a)
#Resource metadata of each Triggers
print(b)Output
#List of Triggers
