## AI overview

SK Telecom describes its journey from Hive-based Trino deployments to Iceberg after encountering scaling and performance problems. The company used Trino across Hadoop and HDFS-based data platforms, collected query plans, JMX statistics, system metrics, and logs, and built a dashboard to investigate blocked queries and cluster behavior.

## Source excerpt

This post comes from the second half of Trino Summit 2022 session. Our friends JaeChang and Jennifer from SK Telecom traveled across the globe from South Korea to join us in person! SK Telecom recently had some issues scaling Trino on the Hive model, among other issues that come with Hive. While some initial tweaking helped speed things up, it ultimately never solved the problem. After switching to Iceberg, SK Telecom ran initial performance tests with some very impressive results. In this talk, Jennifer and JaeChang describe their journey to Iceberg with Trino.
