How to Export Redshift Tables to S3 in Iceberg Format
Redshift to S3 Iceberg Migration - Preferably using Spark
Published Feb 5, 2025
I’m new to AWS and need to export tables from Amazon Redshift to S3 in Iceberg format. Since Redshift’s
UNLOAD
command only supports Parquet, CSV, and JSON, I’m unsure of the best way to achieve this.Would it be better to:
- Unload as Parquet first, then use an AWS service like Glue or EMR to convert and store it in Iceberg format?
- Directly write to Iceberg format using AWS Glue or another tool?
If either of these approaches works, I’d really appreciate a step-by-step guide on how to set it up. My priority is a cost-effective and scalable solution, so I’d love to know the best tools and best practices to use.
Any insights or recommendations would be greatly appreciated! Thanks in advance!
