Data sources - Amazon Redshift

Amazon Redshift will no longer support the creation of new Python UDFs starting Patch 198. Existing Python UDFs will continue to function until June 30, 2026. For more information, see the blog post .

Data sources

You can load data from text files in an Amazon S3 bucket, in an Amazon EMR cluster, or on a remote host that your cluster can access using an SSH connection. You can also load data directly from a DynamoDB table.

The maximum size of a single input row from any source is 4 MB.

To export data from a table to a set of files in an Amazon S3, use the UNLOAD command.
