Just for a bit of context, this is the output of running cloc on the Flink codebase: ----------------------------------------------------------------------------------- Language files blank comment code ----------------------------------------------------------------------------------- Java 4609 126825 185428 519096
=> 704,524 lines of code + comments/javadoc When I apply the google style to the Flink code base using https://github.com/google/google-java-format I get these commit statistics: 4577 files changed, 647645 insertions(+), 622663 deletions(-) That is, a change to the Google Code Style would touch roughly over 90% of all code/comment lines. I would like to have a well defined code style, such as the Google Code style, that has nice tooling and support but I don't think we will ever convince enough people to do this kind of massive change. Even I think it's a bit crazy to change 90% of the code base in one commit.
