 <para>Manifests are grouped by (partition_spec_id, content) — data and delete manifests are never merged together. Within each group, a greedy bin-packing algorithm combines manifests up to target_size_bytes. The bin that contains the newest manifest for that content type is protected by min_count_to_merge: if it has fewer than that many items it is passed through unchanged.</para>
