## Summary - Route DV-enabled partial-update and aggregation splits through the existing raw/KV split selection instead of rejecting every non-materialized plan. - Read only fully materialized compacted splits raw. Apply per-file DVs before key merging for L0, non-raw, legacy, or retract-containing splits. - Keep the existing no-DV behavior for these merge engines. This is a read-side change for Java-written DV tables. Rust DV compaction writes for partial-update and aggregation remain unsupported and are not enabled by this PR. ## Tests - Added real-file MOR cases for partial-update and aggregation, including post-merge value predicates and projection. - Added attached-DV cases covering compacted raw reads, compacted + L0 merge, and disjoint raw + merge splits in one read. - Updated split routing tests for non-raw, legacy, and retract-containing DV files. - cargo test -p paimon table::kv_file_reader:: --lib --no-default-features --features storage-memory,storage-fs (34 passed) - cargo test -p paimon table::table_read:: --lib --no-default-features --features storage-memory,storage-fs (13 passed) - cargo test -p paimon table::table_scan:: --lib --no-default-features --features storage-memory,storage-fs (110 passed) - cargo fmt --all --check; git diff --check -- This is an automated message from the Apache Git Service.
