## Which issue does this PR close? - Closes https://github.com/apache/datafusion/issues/15384 ## Rationale for this change Commit https://github.com/apache/datafusion/commit/0f4b8b136ceb9132fd6b6595bd6a09a09707f5d9 (https://github.com/apache/datafusion/pull/13953) introduced a new optimized evaluation mode for CASE expression with exactly one WHEN-THEN clause and ELSE clause being present. Apparently, the new mode did not take into account expensive or fallible expressions, as it unconditionally evaluated both branches. This is definitely incorrect for fallible expressions. For these, fallback to the original execution mode. ## What changes are included in this PR? fix so that CASE is lazy again ## Are these changes tested? slt ## Are there any user-facing changes? yes -- This is an automated message from the Apache Git Service.
