The files are stored as raw text in a dedicated Amazon S3 bucket. Each object has a key of the form year-month-day_log_HHmmss.txt where HHmmss represents the time the log file was initially created. A table was created in Amazon Athena that points to the S3 bucket. One-time queries are run against a subset of columns in the table several times an hour.<br \/>\nA data analyst must make changes to reduce the cost of running these queries. Management wants a solution with minimal maintenance overhead.<br \/>\nWhich combination of steps should the data analyst take to meet these requirements? (Choose three.)<br \/><strong><br \/>A.<\/strong> Convert the log files to Apache Avro format.<br \/><strong>B.<\/strong> Add a key prefix of the form date=year-month-day\/ to the S3 objects to partition the data.<br \/><strong>C.<\/strong> Convert the log files to Apache Parquet format.<br \/><strong>D.<\/strong> Add a key prefix of the form year-month-day\/ to the S3 objects to partition the data.<br \/><strong>E.<\/strong> Drop and recreate the table with the PARTITIONED BY clause.
