RELEASE NOTE

Information Description
Version V3.1.1_CE
OBServer RPM version oceanbase-ce-3.1.1-1

About this version

In V3.1.1, we have strengthened OceanBase in these fields: kernel compatibility, tools, interfaces, backup and recovery, open-source OS, usability. We will continue to enhance the open-source productization capabilities. Core enhancements and improvements are as follows.

  1. MySQL compatibility: Supported MySQL5.7 driver protocol, Common Table Expression (CTE), several compatible functions. And supported migrating data from MySQL OceanBase Database directly.
  2. High availability: Supported for physical backup and recovery, cluster-level backup, and tenant-level recovery. You can back up production data at high speed and flexibly select recovery methods according to scenarios and needs.
  3. Usability: Released administrator tool ob_admin and error code parsing tool ob_error to provide more convenient and flexible problem analysis and processing capabilities. OBD supported deployment based on system resources and multiple Benchmark testing frameworks.
  4. Interface: Released TABLE API interface, supported direct KV access, high-performance storage access. Released REDO log interface CDC, you can connect your data with third-party data easily to do data conversion, extraction, and framework synchronization.
  5. Tools: Supported Prometheus, production system operation, and maintenance monitoring. Supported Dbeaver, developer client tools, DataX, Canal, Dataworks data development governance framework, MySQL, and OceanBase data migration. Released small-size Docker. Supported almost all major Linux distributions and installation and deployment for 8+ distributions of OS and 12+ versions.

Compatibility changes

Parameter name Original default value Modification type New default value Description
minor_freeze_times 5 Modification 100 Avoid triggering frequent merges
freeze_trigger_percentage 70 Modification 30 Reduce the risk of excessive cluster memory consumption. Decreasing this value dumps earlier to release memory, but dumping becomes more frequent.
enable_merge_by_turn TRUE Modification FALSE By default, we recommend that you merge multiple zones at the same time. Merging by turn needs different zones to avoid response time increase during merges.
trace_log_slow_query_watermark 100ms Modification 1s The original default value 100ms is not reasonable. The performance decreases in high pressure.
clog_sync_time_warn_threshold 100ms Modification 1s The original default value 100ms is not reasonable. The performance decreases in high pressure because too many log files are produced.
enable_one_phase_commit TRUE Modification FALSE Deprecated in the new version.
enable_pg FALSE Deletion -- Deprecated in the new version.
_enable_split_partition FALSE Deletion -- Deprecated in the new version.
