### Feature Request / Improvement I implemented JAVA server programs to manage Iceberg tables using Iceberg JAVA SDK (1.7.1). But I've been suffering from an ungraceful shutdown issue. The servers are running on a Kubernetes cluster. When updating the servers, a SITERM signal is raised. At this time, I want to shut down active requests gracefully. But the ThreadPools is shut down in advance before completing the active requests. Eventually, the active requests are aborted with an executor exception. - related code links https://github.com/apache/iceberg/blob/20b18acb77847153c743bbd63e799f5c61a71d82/core/src/main/java/org/apache/iceberg/util/ThreadPools.java#L133 https://github.com/google/guava/blob/ccd06f2eb635b085ed651edba406116a3665155b/guava/src/com/google/common/util/concurrent/MoreExecutors.java#L238 Internally, the Guava library is used to manage ExecutorService and the library adds a shutdown hook. Currently, there is no way to control the shutdown hook at the application layer. What about adding an option to control the shutdown hook for application-level graceful shutdown? --- ADDITIONAL QUESTION: - Is there any plan to use a virtual thread for the ThreadPools with JDK 21? - I think it can be done conditionally only when the virtual thread is available by a used JDK. ### Query engine None ### Willingness to contribute - [x] I can contribute this improvement/feature independently - [x] I would be willing to contribute this improvement/feature with guidance from the Iceberg community - [ ] I cannot contribute this improvement/feature at this time -- This is an automated message from the Apache Git Service.
