What problem does this PR solve?
Issue Number: close #9348, ref #9103
Problem Summary:
If Min-Max index returns RSResult::All, we will create a EMPTY filter column to make some checks on block structure happy.
tiflash/dbms/src/DataStreams/FilterTransformAction.cpp
Lines 77 to 85 in f0a4087
In LateMaterializationBlockInputStream, filter_column_stream does not execute projecting to remove filter column, and will execute filtering in
tiflash/dbms/src/Storages/DeltaMerge/LateMaterializationBlockInputStream.cpp
Lines 72 to 75 in f0a4087
This result issue #9348.
What is changed and how it works?
Skip filtering for filter column as
tiflash/dbms/src/Storages/DeltaMerge/LateMaterializationBlockInputStream.cpp
Lines 113 to 117 in f0a4087
