OceanBase 4.3.5 CE BP3 HF1 Release

Release overview

On September 4, 2025, OceanBase announced version 4.3.5_CE_BP3_HF1 (commit 8b80b22). The update is packaged as oceanbase-ce-4.3.5.3-103010012025090210 for RPM‑based installations.

What’s fixed?

The vendor‑provided release notes list the following defects that have been resolved:

Memtable in column‑store merge scenarios could remain allocated, leading to memory leaks.
In batch‑write workloads, a row‑conflict rollback could trigger error code 4377.
During cluster expansion, response time (RT) spikes were observed in certain cases.
Automatic partition split for orthogonal buffer tables could hang on the meta‑major phase.
SELECT UNION ALL queries suffered precision loss.
Column‑store queries on integer‑stored columns with filter push‑down could return too few or too many rows.
Vector index operations exhibited several memory‑related issues; memory usage has been optimized.
Global index auto‑split sometimes chose NULL as the split key, causing incorrect results when the query used IS NULL.
When lower_case_table_names=0, some partition split tasks failed to start.

Impact for users

These fixes improve overall stability for mixed workloads, especially those that rely on column‑store tables, vector indexes, and automatic partition management. Users running the CE (Community Edition) can upgrade to mitigate the listed issues.

How to upgrade

The RPM package oceanbase-ce-4.3.5.3-103010012025090210 can be installed via the standard yum/dnf workflow. Review the official upgrade guide for any required configuration changes, particularly if you have custom lower_case_table_names settings.
