### Search before asking - [x] I have searched in the [issues](https://github.com/apache/amoro/issues?q=is%3Aissue) and found no similar issues. ### What would you like to be improved? In our long-running ams process we see too many OSS/HTTP connection pools. Heap analysis shows a very large number of org.apache.http.impl.conn.PoolingHttpClientConnectionManager, which suggests Iceberg FileIO (or its underlying HTTP client) is being created per table and not reused. Since FileIO is expected to be thread-safe, we think FileIO (or at least the underlying HTTP/OSS client) should be shared across tables within the same catalog to avoid excessive pools, memory usage, and sockets. ### How should we improve? Add catalog-scoped reuse/caching of FileIO (or its internal HTTP client/connection manager), so tables with the same catalog/config share the same instance and it’s closed only on catalog/service shutdown. ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Subtasks _No response_ ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
