[GitHub] [hudi] beyond1920 commented on pull request #8051: [HUDI-5851] Improvement of data skipping, only converts expressions to evaluators once

beyond1920 commented on PR #8051:
URL: https://github.com/apache/hudi/pull/8051#issuecomment-1453158013

   @danny0405 Please see `FileIndex#candidateFilesInMetadataTable`. 
   There is no need to convert filters to evaluators every time this method is executed.
   BTW, the main goal of this pr is actually to refactor `ExpressionEvaluators`,  split into 2 phase: convert expression to evaluators, evaluate whether it's possible to match based on the column stats.
