[GitHub] [druid] rohangarg opened a new pull request, #14220: Fix planning in CASE expressions with complex WHEN and ELSE expressions
rohangarg opened a new pull request, #14220:
URL: https://github.com/apache/druid/pull/14220
Using expressions like `NVL(x, '') NOT IN ('y', '')` in filters produce an incorrect filter currently. Calcite converts this expression into a `CASE` expression. This changes fixes that bug by using better planning mechanisms for planning the `WHEN` and `ELSE` clauses of the case expression.
