@QiangCai I have queries related to this PR.
1. If user has not mentioned any sort column then it will go to old flow
(sorting based on all dimension column) or data wont be sorted ?
2. If data is not sorted We cannot use B+ tree we need to use some other
linear data structure like array or linked list, i have not seen any changes
related to this.
2. Btree is created based on sort column, so based on this pr we need to
update the btree loading as only sort column will participate on creating the
Btree.
3. How you creating start key and end key as only sort column can
participate on both the keys. Btree jump will not work if other columns (except
sort columns) are participating in start and end key.
