🚨 Interview Question for Database Professionals 🤔



Have you ever attended a technical interview where you gave multiple correct answers, but the interviewer was still not satisfied because they were expecting only one specific answer that they already had in mind? 🤷‍♂️



💡 In the real world, there isn't always a single "correct" solution.

A DBA may solve the same production issue differently based on:



🏢 Business requirements

🌐 Environment

⏱️ Downtime constraints

👨‍💻 Experience

👥 Team standards

⚖️ Risk assessment



🎯 Many heads, many minds, many approaches.



If a solution is technically correct, follows best practices, and achieves the business objective, shouldn't it be considered a valid answer? ✅



❓ Should interviewers evaluate a candidate's thought process, reasoning, and problem-solving ability instead of expecting only the answer they already have in mind?



💬 I'd love to hear your thoughts from both interviewers and candidates.

🔥 Real PostgreSQL Interview Challenge: Can You Partition a 7 TB Table with ZERO Downtime?



Imagine you have a 7 TB PostgreSQL table running in a production environment with 24×7 traffic.



Question: How would you convert this existing non-partitioned 7 TB table into a partitioned table with zero or near-zero downtime? Is it really possible? If yes, what approach would you use?



Consider factors such as:



1. Data migration strategy

2. Ongoing DML (INSERT/UPDATE/DELETE)

3. Application impact

4. Cutover strategy

5. Rollback plan



PostgreSQL native features vs third-party tools



💬 There are multiple approaches, each with its own trade-offs.

What would be your solution?
