lszskye opened a new pull request, #216:
URL: https://github.com/apache/paimon-cpp/pull/216
### Purpose
This change:
(1) Improves shared-shredding MAP reading performance
(2) Fix incorrect ORC read-size estimation that prevents file prefetching
when prefetch is enabled
(3) Fix shared-shredding MAP values with nested dictionary-encoded types.
### Tests
- Added selected-key STRUCT projection tests that verify primitive
value-buffer sharing.
- Added ORC coverage for MAP values with `list<dictionary-encoded string>`.
- Added `OrcFileBatchReaderTest` cases for:
- primitive LIST
- deeply nested LIST
- primitive MAP
- deeply nested MAP
- STRUCT projection containing LIST and MAP fields
- unsupported partial projection inside LIST and MAP
### API and Format
No public API changes.
