Optimal Null Value Handling in Java Object Updates Post-UpdateStrategy Change

Context

Following the shift in our global UpdateStrategy to 'ignore', we encounter a new challenge: preventing unwanted null value assignments during object updates. This change necessitates a reevaluation of our approach to ensure data integrity without compromising on performance.

Strategies Under Consideration

Direct Assignment

Pros: Straightforward and minimalistic.
Cons: High risk of null value propagation, potentially leading to data loss.

Conditional Checking

Pros: Explicit control over value assignment.
Cons: Increases code complexity and verbosity.

Utilization of Optional

Pros: Cleaner syntax, avoids explicit null checks.
Cons: Potentially reduces readability due to more complex lines.

Hutool's BeanUtil.copyProperties

Pros: Reduces boilerplate code significantly.
Cons: Introduces a third-party dependency and may degrade performance due to reflection, particularly after our update strategy shift.

Key Considerations

• Performance Impact: Special attention must be given to the reflection costs associated with Hutool's approach, given our high-volume data context.
• Maintainability vs. Efficiency: We need to balance the ease of maintainability with the efficiency of the code, considering the new 'ignore' strategy.
• Dependency Management: We must be cautious about introducing new dependencies and consider using similar functionalities from existing libraries like Guava.

Seeking Input

I invite community input on these strategies to arrive at a consensus that honors our commitment to robust and performant code. Your insights and suggestions are invaluable as we navigate this change.

I'll proceed with Conditional Checking to align with our 'ignore' strategy change and maintain data integrity. Your thoughts on this are welcome!
