Question 1

How to compile and run MiniOB from source on Linux?

Accepted Answer

Follow the build instructions in the documentation, which cover dependencies and compilation steps, but be prepared for potential issues with newer system libraries compared to the cloud environment.

Question 2

MiniOB vs SQLite for learning database internals: which is better?

Accepted Answer

MiniOB is tailored for educational deep dives into kernel implementation with simplified code, while SQLite is a full-featured, embeddable database. Choose MiniOB for hands-on coding of core modules, and SQLite for practical application development.

Question 3

What transaction management does MiniOB support?

Accepted Answer

It implements basic MVCC for transaction isolation, but lacks advanced features like distributed transactions or complex rollback mechanisms, as noted in the simplified architecture.

Question 4

Can I use MiniOB for a small personal project?

Accepted Answer

It's possible for learning purposes, but the lack of concurrency and security features makes it unsuitable for production deployments or projects requiring robust data handling.

Question 5

How do I participate in the OceanBase competition with MiniOB?

Accepted Answer

Use the MiniOB training platform to submit code for testing, and refer to the competition FAQ and video tutorials on the OceanBase website for problem-solving guidance and updates.

Question 6

Does MiniOB support SQL joins and subqueries?

Accepted Answer

Support is limited or partial, as the optimizer is only partially implemented; it focuses on fundamental SQL parsing and execution rather than advanced query features.
