Loading compressed data files from Amazon S3 - Amazon Redshift
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Amazon Redshift will no longer support the creation of new Python UDFs starting November 1, 2025. If you would like to use Python UDFs, create the UDFs prior to that date. Existing Python UDFs will continue to function as normal. For more information, see the blog post .

Loading compressed data files from Amazon S3

To load data files that are compressed using gzip, lzop, or bzip2, include the corresponding option: GZIP, LZOP, or BZIP2.

For example, the following command loads from files that were compressing using lzop.

COPY customer FROM 's3://amzn-s3-demo-bucket/customer.lzo' 
IAM_ROLE 'arn:aws:iam::0123456789012:role/MyRedshiftRole'
DELIMITER '|' LZOP;
Note

If you compress a data file with lzop compression and use the --filter option, the COPY command doesn't support it.
