  3. Subject does not end with a period
  4. Subject uses the imperative mood ("add", not "adding")
  5. Body wraps at 72 characters
  6. Body explains "what" and "why", not "how"

Documentation

  • All the public functions and the classes in the PR contain Javadoc that explain what it does

Should we worry about overflow by (rows * remainingMem)?

[gszadovszky]

I've felt it as a low risk. We are talking about pages here so neither the row count nor the used memory should be too high that this would overflow.

Same as gszadovszky +1
