A company runs hourly ETL jobs that append data to an S3 table partitioned by hour. The AWS Glue Data Catalog table is updated by a crawler that runs every 6 hours. Analysts using Athena complain that queries for the most recent 2 hours return no data. The company wants to minimize cost and operational overhead while ensuring data is queryable within 15 minutes of arrival. What should they do?

Use Athena's 'MSCK REPAIR TABLE' command on a schedule every 15 minutes.

Increase the crawler frequency to every 15 minutes.

Use S3 event notifications to trigger a Lambda function that runs the crawler on new data.

Enable partition indexing on the table so that new partitions are automatically detected.

What is the primary function of an AWS Glue crawler?

To automatically discover the schema of data in a data store and populate the data catalog with table definitions.

To copy data from on-premises systems to Amazon S3.

To monitor the performance of AWS Glue jobs and send alerts.

To run ETL jobs that transform data from one format to another.
