Don't repeat yourself. same as the line 50, maybe we need a function
| std::vector<bool> _is_upper_keys_included; | ||
| // contains condition on key columns in agg or unique table or all column in dup tables | ||

why change unique_ptr， need more malloc operator

because I change tablet schema as a parameter in Conditions constructor and remove set tablet schema method because the condtion should always have a tablet schema and should not be changed. But tablet schema is not required in reader's constructor.

I think, it is useless. Because it is never be set, but collector depend on it and many logic depend on it, I do not know the meaning of the flag.

_rs_version_map in Tablet is much more efficient.

Should we hide index in the TabletSchema? We can use a function like this _schema->get_clolumn_by_unique_id(tcond.column_unique_id).
