Resolution Use bucketing to set the file size or number of files in a CTAS query. workgroup's details. If To demonstrate this feature, I’ll use an Athena table querying an S3 bucket with ~666MBs of raw CSV files (see Using Parquet on Athena to Save Money on AWS on how to create the table (and learn the benefit of using Parquet)). You can also use the Oracle CREATE TABLE AS statement to create a table from an existing table by copying the existing table's columns.
