Here is a brief summarize of the project: COMPLETED WORK Simple implementation of decorrelation framework - algorithm implementation for converting correlated subqueries with three main components: + DependentJoinRewriter - Converts subqueries into dependent joins + DependentJoinDecorrelator - Removes correlations using advanced unnesting + Duplicate elimination optimizer(WIP) - Removes redundant operations REMAINING WORK + Fix corner cases in existing tests - Ensure all previously passing tests in subquery.slt work with the new decorrelation framework, including edge cases that currently fail + Add configuration variable - Implement a config variable to manually enable/disable the decorrelate_general functionality, allowing users to toggle between old and new subquery processing + Add complex test cases - Implement support for more sophisticated scenarios that the original system couldn't handle (e.g., TPC-DS benchmark queries and other complex correlated subquery patterns) -- This is an automated message from the Apache Git Service.
