In August 2020 Michael started a discussion[1] about renaming the 'master' branch in Git to 'main'. A majority of the community seemed to be in favor, although some people did not agree with the change.
If I recall correctly, we did not move forward with the rename at that time in part because of tooling: GitHub tooling was not mature enough to guarantee that the change would be smooth. I now believe the tooling is mature. I have migrated several personal projects, and GitHub makes it very easy. I propose that we move forward with renaming the 'master' branch in the calcite, calcite-avatica and calcite-avatica-go repositories. I propose that we do calcite-avatica first, because it is less used than calcite. Julian [1] https://lists.apache.org/thread/7f2kpkf8lrq0mmt46lb2orsh39kq7dbs
