Simplify data ingestion from Amazon S3 to Amazon Redshift using auto-copy
- Amazon Redshift is a cloud data warehouse that can analyze exabytes of data, and data ingestion is the process of getting data into Amazon Redshift. Amazon Redshift launched auto-copy support to simplify data loading from Amazon S3 to Amazon Redshift. By creating auto-copy jobs, it is now possible to set up continuous file ingestion rules to track your Amazon S3 paths and automatically load new files into Amazon Redshift without additional tools or custom solutions.
- The auto-copy feature in Amazon Redshift uses the S3 event integration to simplify automatic data loading from Amazon S3 with a simple SQL command. It can be quickly set up using a simple SQL statement in JDBC/ODBC clients.
- Auto-copy jobs offer automatic and incremental data ingestion from an Amazon S3 location without the need to implement a custom solution. Users can now load data from Amazon S3 automatically without having to build a pipeline or using an external framework.
- Auto ingestion is enabled by default on auto-copy jobs. Files already present at the S3 location will not be visible to the auto-copy job.
- Amazon Redshift auto-copy jobs keep track of loaded files and minimize data duplication while also having automatic error handling of bad quality data files.
- Customers can also load an Amazon Redshift table from multiple data sources and maintain multiple data pipelines for each source/target combination.
- To monitor and troubleshoot auto-copy jobs, Amazon Redshift provides a range of system tables for users to get summary details, exception details, error details, or the status and details of each file that was processed by a auto-copy job.
- Some of the main things to consider when using auto-copy are that existing files in Amazon S3 prefix are not loaded, and the following features are unsupported: MAXERROR parameter, manifest files, and key-based access control.
- GE Aerospace uses AWS analytics and Amazon Redshift to enable critical business insights that drive important business decisions and noted that auto-copy simplifies data pipelines, accelerates analytics solutions, and lets them spend more time adding value through data.
- Overall, Amazon Redshift auto-copy feature offers a simple and effective way to ingest data from Amazon S3 to Amazon Redshift, and users can begin ingesting data to Redshift from S3 with simple SQL commands and gain access to the most up-to-date data.
