How to use Boto3 to delete a specific version of table from AWS Glue Data catalog?

Boto3PythonServer Side ProgrammingProgramming

Problem Statement − Use boto3 library in Python to delete a table of specific version, created in your account.

Example − Delete a table ‘security’ version 1 from database ‘test’ that is created in your account.

Approach/Algorithm to solve this problem

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

Step 2 − Pass the parameter database_name, table_name and version_id 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_table_version function and pass the database_name as DatabaseName parameter, table_name as TableName parameter and version_id as VersionId parameter. Please keep remember, VersionId is string so it should be passed in ‘ ’ and user can’t delete latest version of a table. Only the old version of a table can be deleted if user wants to delete latest version then drop the table using function delete_table.

Step 6 − It will delete the old specific version of table and return the response metadata.

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

Example

Use the following code to delete a specific version of table from AWS Glue database −

import boto3
from botocore.exceptions import ClientError

def delete_a_table_version_from_database(database_name, table_name, version_id:str):
   session = boto3.session.Session()
   glue_client = session.client('glue')
   try:
      response = glue_client.delelte_table_version(DatabaseName= database_name, Name = table_name, VersionId = version_id)

   return response
      except ClientError as e:
         raise Exception( "boto3 client error in delete_a_table_version_from_database: " + e.__str__())
   except Exception as e:
      raise Exception( "Unexpected error in delete_a_table_version_from_database: " + e.__str__())
print(delete_a_table_version_from_database("test","security","1"))

Output

{'ResponseMetadata': {'RequestId': '7aa7c3cb…………….-…….8a238c',
'HTTPStatusCode': 200, 'HTTPHeaders': {'date': 'Sun, 21 Feb 2021
04:58:04 GMT', 'content-type': 'application/x-amz-json-1.1', 'contentlength': '2', 'connection': 'keep-alive', 'x-amzn-requestid': '7aa7c3cbf611-494e-b923-8610318a238c'}, 'RetryAttempts': 0}}
