Problem Statement − Use boto3 library in Python to get details of a connection present in AWS Glue Data catalog.Example − Get the details of a connection definition, ‘aurora-test’.Approach/Algorithm to solve this problemStep 1 − Import boto3 and botocore exceptions to handle exceptions.Step 2 − Pass the parameter connection_name whose definition needs to check.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_connection function and pass ... Read More
Problem Statement − Use boto3 library in Python to check whether a bucket does not exist using waiter functionality. For example, use waiters to check whether Bucket_2 does not exist in S3.Approach/Algorithm to solve this problemStep 1 − Import boto3 and botocore exceptions to handle exceptions.Step 2 − Use bucket_name as the parameter in the function.Step 3 − Create an AWS session using boto3 library.Step 4 − Create an AWS client for S3.Step 5 − Now create the wait object for bucket_not_exists using get_waiter function.Step 6 − Now, use the wait object to validate whether the bucket does not exist. By default, ... Read More
When a user wants to use wait functionality to validate whether a key in a bucket exists or not in programming code.Problem Statement − Use boto3 library in Python to check whether a key exists in a bucket, using waiters functionality. For example, use waiters to check whether a key test.zip exists in Bucket_1.Approach/Algorithm to solve this problemStep 1 − Import boto3 and botocore exceptions to handle exceptions.Step 2 − bucket_name and key are two parameters in function.Step 3 − Create an AWS session using boto3 library.Step 4 − Create an AWS client for S3.Step 5 − Now create the ...

Problem Statement − Use boto3 library in Python to run a glue job. For example, run the job run_s3_file_job.Approach/Algorithm to solve this problemStep 1 − Import boto3 and botocore exceptions to handle exceptions.Step 2 − job_name is the mandatory parameters while arguments is the optional parameter in function. Few jobs take arguments to run. In that case, arguments can be passed as dict.For example: arguments = {‘arguments1’ = ‘value1’, ‘arguments2’ = ‘value2’}If the job doesn’t take argument, then just pass the job_name.Step 3 − Create an AWS session using boto3 library. Make sure region_name is mentioned in default profile. If ... Read More
Problem Statement − Use boto3 library in Python to delete a database, created in your account.Example − Delete a database ‘Portfolio’ that is created in your account.Approach/Algorithm to solve this problemStep 1 − Import boto3 and botocore exceptions to handle exceptions.Step 2 − Pass the parameter database_name that should be deleted from AWS Glue Catalog.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 delete_database function ... Read More

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 ... Read More
Problem Statement − Use boto3 library in Python to get details of a classifier from AWS Glue Data catalog. For example, get the details of a classifier – ‘xml-test’.Approach/Algorithm to solve this problemStep 1 − Import boto3 and botocore exceptions to handle exceptions.Step 2 − Pass the parameter classifier_name whose details are to be checked.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_classifier and pass ... Read More
Problem Statement − Use boto3 library in Python to get the status of a migrating operation.Example − Get the status of migration operation in an account.Approach/Algorithm to solve this problemStep 1 − Import boto3 and botocore exceptions to handle exceptions.Step 2 − Pass the parameter catalog_id whose migrating status needs to check. However, this is an optional parameter. If it is not provided, by default it checks for logged in user account whether migration is in progress or completed. catalog_id is nothing other than user account id.Step 3 − Create an AWS session using boto3 library. Make sure region_name is ... Read More
