* Reverse lookup fixes and enhancements. 1) Add a "mayIncludeUnknown" parameter to DimFilter#optimize. This is important because otherwise the reverse-lookup optimization is done improperly when the "in" filter appears under a "not", and the lookup extractionFn may return null for some possible values of the filtered column. The "includeUnknown" test cases in InDimFilterTest illustrate the difference in behavior. 2) Enhance InDimFilter#optimizeLookup to handle "mayIncludeUnknown", and to be able to do a reverse lookup in a wider variety of cases. 3) Make "unapply" protected in LookupExtractor, and move callers to "unapplyAll". The main reason is that MapLookupExtractor, a common implementation, lacks a reverse mapping and therefore does a scan of the map for each call to "unapply". For performance sake these calls need to be batched. * Remove optimize call from BloomDimFilter. * Follow the law. * Fix tests. * Fix imports. * Switch function. * Fix tests. * More tests. |
