> In DataMapChooser, Carbondata try to choose and combine datamap for expressions. In some scenario, it will generate `TrueConditionalResolverImpl` to wrap the sub-expression, which will cause data scan on the blocklet which can be skipped (For `TrueConditionalResolverImpl`, the  `TrueFilterExecutor` will always cause scanning the data even it simply wraps a range expression).
