@viirya, BTW, do you mind fixing the PR description to explain what this PR specifically improves? > This patch proposes to add more optimization to `UpdateFields` expression chain. Seems like this PR does not describe what exactly optimizes. Is my understanding correct that this PR proposes two separate optimizations? - Deduplicates `WithField` at `UpdateFields` - Respect nullability in input struct at `GetStructField(UpdateFields(..., struct))`, and unwrap if-else. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
