I've been investigating the OOM issue in the Trino coordinator. It turns out that a significant portion of memory usage comes from the statistics stored in `DeleteFileIndex`. To address this, I propose we avoid copying the stats - just like we already do for DataFile in the `ManifestGroup#createFileScanTasks` method. https://github.com/apache/iceberg/blob/5a096b764fa88e4a71d0d53e90aaa58ecb6d6db8/core/src/main/java/org/apache/iceberg/ManifestGroup.java#L364-L365 Related Slack thread: https://apache-iceberg.slack.com/archives/C03LG1D563F/p1747988880908899 -- This is an automated message from the Apache Git Service.
