Conversation
- Add a block fast path for explode-like table functions to expand
contiguous nested ranges without per-row get_value()
- Fall back to the original row-wise path when the nested range is
non-contiguous or unsupported
- Add/extend unit tests to cover fast path and fallback cases
Test: ./run-be-ut.sh --run
--filter='TableFunctionOperatorTest.*:UnnestTest.*'
Performance :
Simple Array: 10.1s -> 5.1s
Nested Array: 100.2s -> 20.1s
