Runs can be monitored through the AWS Glue console, Amazon CloudWatch metrics, and logs. It can be enabled via the AWS Glue console, AWS CLI, or AWS SDKs. ## Full article daily.dev links to this article rather than hosting it.

Enable it through the AWS Glue console, AWS CLI, or AWS SDKs, either for individual tables or for all tables in your Data Catalog. Once enabled, it continuously compacts small files, removes snapshots past retention settings, and deletes unreferenced files in the background. You can monitor each run via the AWS Glue console, Amazon CloudWatch metrics, and logs. _Teams tuning Iceberg performance on AWS track rollout details like regional availability on daily.dev._ ### Why does my Apache Iceberg table in a data lake get slower over time? Iceberg tables accumulate small files, old snapshots, and unreferenced files with every write, which slows queries and increases storage costs over time. AWS Glue's table optimization feature addresses this by compacting small files, expiring old snapshots per retention settings, and deleting orphaned files automatically in the background. _Anyone managing Iceberg table sprawl can follow optimization updates like this on daily.dev._ ## Similar posts on daily.dev - [Simplified permissions for Amazon S3 Tables and Iceberg materialized views are now available in AWS GovCloud \(US\) Regions](https://daily.dev/posts/simplified-permissions-for-amazon-s3-tables-and-iceberg-materialized-views-are-now-available-in-aws--me0dinp3d) · AWS · 0 upvotes · 0 comments - [Apache Iceberg on AWS: Glue Catalog, Athena, EMR, and S3 Tables](https://daily.dev/posts/apache-iceberg-on-aws-glue-catalog-athena-emr-and-s3-tables-qgxux89im) · BigData Boutique blog · 0 upvotes · 0 comments - [Apache Iceberg on AWS, Part 1: What It Is, Why You Need It, and How It Works](https://daily.dev/posts/apache-iceberg-on-aws-part-1-what-it-is-why-you-need-it-and-how-it-works-fqcctfmbr) · Infostrux · 2 upvotes · 0 comments - [AWS Glue 6.0 delivers 30% price reduction and Iceberg v3 support](https://daily.dev/posts/aws-glue-6-0-delivers-30-price-reduction-and-iceberg-v3-support-leaq7lqlv) · AWS · 0 upvotes · 0 comments --- Tags: [#aws](https://daily.dev/tags/aws), [#apache-iceberg](https://daily.dev/tags/apache-iceberg), [#data-lake](https://daily.dev/tags/data-lake) [View this post on daily.dev](https://daily.dev/posts/aws-glue-data-catalog-now-supports-apache-iceberg-table-optimization-in-the-us-west-n-california--2xx8k21m9) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"AWS Glue Data Catalog now supports Apache Iceberg table optimization in the US West (N.
