Version information

• Release date: April 06, 2023

• Version: V3.2.11 BP1

• RPM version: obproxy-3.2.11.0-20230406144131

V3.2.11

Version information

• Release date: April 03, 2023

• Version: V3.2.11

• RPM version: obproxy-3.2.11.0-20230403112629

Overview

• ODP can obtain the client IP addresses and allowlist settings across virtual private clouds (VPCs) by using the OceanBase 2.0 protocol.

• IP address-based routing is supported.

• Parsing of hexadecimal data is supported.

  Notice

  Text binary data will double the data length of the entire request. If ODP fails to parse the information required for partition calculation when the request buffer exceeds the size limit, which is 4,096 KB by default, ODP will continue with random routing. In this case, you can increase the size of the request buffer or allow random routing for these requests.

• The subpartition keyword is supported.

• When ODP actively disconnects from the client, an error packet is sent to the client.

Bug fixes

• Fixed the issue of core dumps related to prepared statements.

• Fixed the issue where internal connections are hung.

• Fixed the issue where concurrent ObMysqlClient connections are not released.

• Fixed the issue where disconnection occurs when case sensitivity is enabled for prepared statements.
