Architecture Decision Records (ADRs)

This directory contains Architecture Decision Records for the WorkerSQL project. ADRs document important architectural decisions, their context, and rationale.

ADR Template

When creating new ADRs, use the following template:

# ADR-XXX: [Title]

## Status

[Proposed | Accepted | Deprecated | Superseded]

## Date

YYYY-MM-DD

## Context

[Describe the forces at play, including technological, political, social, and
project local. This is the story explaining the problem we are trying to solve.]

## Decision

[Describe our response to these forces. This is the actual decision made.]

## Rationale

[Describe why this decision was made. Include alternative options considered and
why they were rejected.]

## Consequences

[Describe the resulting context, after applying the decision. All consequences
should be listed here, not just the "positive" ones.]

## References

[List any references, links, or sources that informed this decision.]

Guidelines

When to Write an ADR

• Significant architectural or design decisions
• Technology stack choices
• Security architecture decisions
• Performance or scalability trade-offs
• Changes to existing architectural decisions

ADR Lifecycle

1. Proposed: Decision is under consideration
2. Accepted: Decision has been made and implemented
3. Deprecated: Decision is no longer recommended but may still be in use
4. Superseded: Decision has been replaced by a newer ADR

Best Practices

• Keep ADRs concise but comprehensive
• Focus on the decision, not implementation details
• Include the context that led to the decision
• Document alternatives considered
• Update status as decisions evolve
• Link related ADRs when appropriate
