DBLE 3.0 Planning Overview and Community Q&A Summary

The final DBLE open class session was held on Tuesday, May 12, featuring a live presentation titled "DBLE 3.0 Planning Overview and Community Q&A" by DBLE project lead Yan Huqing (Lan Yin). The session concluded the DBLE open‑class series.

During the live broadcast, the speaker introduced the DBLE 3.0 roadmap and answered pre‑collected community questions. Additional questions were gathered in real time, though not all could be addressed due to time constraints.

All PPT slides and the video recording of the session are now available for download via the provided Baidu Cloud link (extraction code: 8hbo) and Youku video link. The community Q&A section lists the questions and concise answers.

Key topics covered include:

More standardized connection pool.

Enhanced read‑write separation capabilities.

More flexible and user‑friendly management commands.

Customizable firewall features.

Improved configuration file structure.

Distributed transaction interfaces.

Code module tracing.

Support for MySQL 8.0.

Representative Q&A highlights:

DBLE’s suitability for large‑scale OLTP workloads with data sharding.

MySQL auto‑increment IDs are independent of DBLE’s global sequence.

Distributed transaction support introduces performance overhead that cannot be fully eliminated.

Future plans include custom firewall rules and integration with the TXLE distributed‑transaction framework.

Sharding fields will remain single‑column; multiple columns should be combined into a redundant column for custom splitting.

Physical backup strategies and pause/resume mechanisms are documented in the official DBLE docs.

High‑availability can be achieved with any stateless HA tool; DBLE itself is essentially stateless.

Commercial version offers visual configuration and easier deployment for large‑scale clusters.

The article also points readers to the DBLE technical discussion group (QQ 669663113) for further questions and encourages community participation.
