What commenters say

• The advice on logging and metrics is valuable, but it's essential to strike a balance between logging too much and too little to avoid performance issues.
• Audit tables can be useful for tracking changes, but they can also be seen as a redundant source of truth and may not always be reliable.
• Converting boolean values to timestamps can be a good pattern, but it should not be applied universally and should be considered on a case-by-case basis.
• Soft deletion can be more of a headache than it's worth, and alternative approaches should be considered.
• Good system design is highly dependent on the specific problem being solved, and general advice may not always be applicable.
• The use of events and event-driven architecture can be beneficial, but it's crucial to avoid overusing events and to consider the trade-offs.
• Simplifying complex systems can be challenging, especially in large organizations, and may require significant effort and resources.
• The importance of understanding the problem domain and the specific requirements of the system cannot be overstated in good system design.
