@alamb this one is the next episode in my quest to squeeze more performance out of case. The TL;DR is that we project away unneeded columns from the record batch to avoid work during filtering. I thought this would be most elegant as a decorator expression, but that's immediately visible externally and as a consequence would need serialisation support. The alternative is that I pull this into CaseExpr, perhaps as a distinct (or wrapping) evaluation mode? Any opinion on the direction in which to proceed? -- This is an automated message from the Apache Git Service.
