GitHub Labels

This guideline describes the best practices related to using Github Labels for Issues and Pull Requests.


The procedure described in this guideline only applies to Polypheny-DB and not to the other projects.

Label categories

Contributors with sufficient permissions on the Polypheny-DB repo can help by adding labels to issues and (to a lesser degree) pull requests:

  • Yellow, A-prefixed labels state which area of the project an issue relates to. Examples: A-core, A-ui, A-stores

  • Light purple, C-prefixed labels represent the category of an issue.

  • Green, E-prefixed labels explain the level of experience working with Polypheny-DB that is necessary to fix the issue.

  • The light orange invalid label marks an issue as being opened in error.

  • Orange, P-prefixed labels indicate a bug’s or issue’s priority.

  • Gray, S-prefixed labels are used for tracking the status of pull requests.

Labeling pull requests

There are mainly two labels that should be used for pull requests:

  • S-waiting-on-review, the pull request is ready to be reviewed. If your PR is not ready, consider using a draft pull request.

  • S-waiting-on-author, the pull request requires changes by the author.

Other possible labels:

  • S-blocked, something is blocking this pull request from being merged. If you assign this label, please also leave a comment that states what is blocking, esp if there is an issue that can be referenced.

  • S-inactive, there has been no activity for some time.


This labeling scheme is based on the Rust language repository. The rust project is dual-licensed under Apache 2.0 and MIT terms.
