The PR does include documentation update: https://github.com/vlsi/calcite/blob/checkerframework/site/develop/index.md#null-safety Fan Liya>I mean that a large PR requires a long time to review. Do you commit to reviewing the change? How much time would it take you to review the change? As I said, the PR was there for several months, and I do NOT believe adding two or six months more would make a difference. Fan Liya>During this time, you have to resolve conflicts many times, which is a Fan Liya>large amount of effort. The added nullability annotations have minimal impact on Calcite API and its behavior. All the existing tests pass, and I change only a few test files. Of course, I do not like the idea of rebasing PR again and again. Just as an example, Calcite 1.25 was released with a significant backward-incompatible change: 998cd83eb 2020-07-08 Julian Hyde [CALCITE-3923] Refactor how planner rules are parameterized 198 files changed, 9018 insertions(+), 5503 deletions(-) The refactor alone was bigger than nullability PR if we compare the number of added and removed lines. Just to remind, "prepare for nullability" is (757 files changed, 7487 insertions(+), 3827 deletions(-)) Vladimir
