issue: #44373 The current commit implements sparse filtering in query tasks using the statistical information (Bloom filter/MinMax) of the Primary Key (PK). The statistical information of the PK is bound to the segment during the segment loading phase. A new filter has been added to the segment filter to enable the sparse filtering functionality.
