Stores information in the following log files: Statements are logged as soon as Amazon Redshift receives them. The following table compares audit logs and STL tables. the wlm_json_configuration Parameter in the You could parse the queries to try to determine which tables have been accessed recently (a little bit tricky since you would need to extract the table names from the queries). We first import the Boto3 package and establish a session: You can create a client object from the boto3.Session object and using RedshiftData: If you dont want to create a session, your client is as simple as the following code: The following example code uses the Secrets Manager key to run a statement. The hop action is not supported with the max_query_queue_time predicate. administrators. The connection and user logs are useful primarily for security purposes. The AWS Redshift database audit creates three types of logs: connection and user logs (activated by default), and user activity logs (activated by the "enable_user_activity_logging" parameter). In RedShift we can export all the queries which ran in the cluster to S3 bucket. Log retention also isn't affected by To set up a CloudWatch as your log destination, complete the following steps: To run SQL commands, we use redshift-query-editor-v2, a web-based tool that you can use to explore, analyze, share, and collaborate on data stored on Amazon Redshift.
