I don't think remapped_slot_ids is needed.
The select_columns contains this information and ignore select column order

…39670) # Proposed changes support cache tablets aggregate result for example SQL 1: ```sql select key, sum(value) from tbl where dt between '2024-08-01' and '2024-08-10' group by key ``` SQL 2: ```sql select key, sum(value) from tbl where dt between '2024-08-5' and '2024-08-15' group by key ``` SQL 1 will update the tablets aggregate result which partition between '2024-08-01' and '2024-08-10'. Then SQL 2 will reuse the tablets aggregate which partition between '2024-08-05' and '2024-08-10', and compute aggregate which partition between '2024-08-11' and '2024-08-15' We only support simple aggregate which not contains join with runtime filter, at present. # How to use ```sql set enable_query_cache=true; ```

Proposed changes
support cache tablets aggregate result
for example
SQL 1:
SQL 2:
SQL 1 will update the tablets aggregate result which partition between '2024-08-01' and '2024-08-10'.
Then SQL 2 will reuse the tablets aggregate which partition between '2024-08-05' and '2024-08-10', and compute aggregate which partition between '2024-08-11' and '2024-08-15'
We only support simple aggregate which not contains join with runtime filter, at present.
