2-9 Technical filling and crash prevention

Preventing architecture collapse

• Architectural collapse is a serious architectural design accident, and it is also the key to our prevention.
• 1. System crash occurs
• 2. Log records, such as: operation logs, error logs, business logs, etc.
• User behavior capture → strive to obtain the user operation chain at the latest time.
• Solve existing problems → technical debt.
• Contain new additions→Reduce the probability of new problems.
• Digging and inspecting dirty data.
• unit test.
• Crash alarm.
• automated test.
• Wider grayscale reach.
• Performance optimization system.
