Overview

Generally, Kafka uses:

That is, JIRA and Confluence are used to describe what should be fixed or changed, and high-level approaches, and pull requests describe how to implement that change in the project's source code.

JIRA

  1. Find the existing Kafka JIRA that the change pertains to.

    1. Do not create a new JIRA if creating a change to address an existing issue in JIRA; add to the existing discussion and work instead

    2. Look for existing pull requests that are linked from the JIRA, to understand if someone is already working on the JIRA

  2. If the change is new, then it usually needs a new JIRA. However, trivial changes, where "what should change" is virtually the same as "how it should change" do not require a JIRA. Example: "Fix typos in Foo scaladoc"

  3. If required, create a new JIRA:

    1. Provide a descriptive Title. "Update web UI" or "Problem in scheduler" is not sufficient. "Kafka support fails to handle empty queue during shutdown" is good.

    2. Write a detailed Description. For bug reports, this should ideally include a short reproduction of the problem. For new features, it may include a design document (or a Kafka Improvement Proposal if it's a major change).

    3. Set required fields.

    4. Do not include a patch file; pull requests are used to propose the actual change.

  4. If the change is a large change, consider inviting discussion on the issue at dev@kafka.apache.org first before proceeding to implement the change.
