Aggregate for risks

Notable Risks

Lack of Test Coverage for New Functionality in PR #22498

Severity: High (3/3)

Rationale

The pull request #22498, which aims to add web vitals collection, lacks any associated test cases. This absence of test coverage is critical because it introduces new functionality that could potentially affect the performance and reliability of the analytics platform.

• Evidence: The PR #22498 does not include any new test files or updates to existing test files.
• Reasoning: Introducing new functionality without adequate test coverage can lead to undetected bugs and issues in production, affecting the reliability and accuracy of the analytics platform.

Next Steps

• Immediately add comprehensive test cases for the new web vitals collection functionality.
• Ensure that these tests cover various scenarios and edge cases to validate the correctness and performance of the new feature.

Prolonged Disagreement in PR #22497

Severity: Medium (2/3)

Rationale

There has been considerable disagreement among team members regarding the architectural changes proposed in PR #22497, which moves query performance polling to its own Celery task. This prolonged disagreement could indicate deeper underlying issues that may affect project timelines and team cohesion.

• Evidence: The discussion thread in PR #22497 shows ongoing debates and lack of consensus on the proposed changes.
• Reasoning: Prolonged disagreements can delay important updates and create friction within the team, potentially impacting overall productivity and project timelines.

Next Steps

• Escalate this discussion to a tech lead or technical executive for resolution.
• Facilitate a meeting to reach a consensus and document the agreed-upon approach to avoid future misunderstandings.

Multiple Rewrites of Source Code Files

Severity: Medium (2/3)

Rationale

Several source code files have undergone multiple rewrites within a short period. This pattern can introduce instability and indicates potential issues with initial design or requirements clarity.

• Evidence: Files such as posthog/models/query_metrics/sql.py and frontend/src/lib/components/DatabaseTableTree/DatabaseTableTree.tsx have seen multiple recent changes.
• Reasoning: Frequent rewrites can lead to code instability, increased likelihood of bugs, and potential technical debt if not managed properly.

Next Steps

• Conduct a review to understand the reasons behind these frequent changes.
• Ensure that requirements are clearly defined and initial designs are thoroughly reviewed before implementation.
• Implement stricter code review processes to catch potential issues early.

Non-Critical PRs Left Open for Several Days

Severity: Low (1/3)

Rationale

Several non-critical pull requests have been left open for several days without any updates or reviews. While not immediately critical, this can slow down development progress and indicate potential bottlenecks in the review process.

• Evidence: PRs such as #22502 (dependency update) have been open for multiple days without significant activity.
• Reasoning: Delays in reviewing and merging non-critical PRs can accumulate over time, leading to slower development cycles and potential backlog build-up.

Next Steps

• Streamline the review process to ensure timely reviews and merges of non-critical PRs.
• Assign specific reviewers or set up automated reminders to address pending PRs promptly.
