During MergingSnapshotProducer commits, ManifestFilterManager reads and materialize every ManifestEntry in memory to determine if manifest entries need to be rewritten. However, the common case is only a small fraction of manifests are modified in a commit. Instead, all manifests can be read in a lightweight projected way way (excluding large stats columns). Then only those manifest entries that need to be rewritten can be read in full. For tables with large numbers of manifests, this can be a significant memory reduction. Benchmarks coming soon. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
