OceanBase

• 4.2.1 BP8 已发布：新增支持日志流副本管理、DBLink指定域名访问、主备租户角色切换验证、主备租户事件展示、事务提交后 Cursor 访问、SM3 加密函数，OBKV 新增响应时间统计直方图、OBKV-HBase 支持列分页、逆序扫描。
• 4.3.2 已发布：OceanBase V4.3.2 是面向 AP 业务的性能增强版本，数据读取、数据分发、数据计算、向量化处理、计划选择全方位改进，AP 类基准测试性能整体提升 10%-15%。引入 Roaringbitmap 数据类型及相关计算表达式，给大数据集合运算和去重场景提供了更优选择。丰富增量旁路导入功能、提升全量旁路导入性能，扩展支持 Parquet 文件外表，加速大规模数据的处理速度。作为一款一体化数据库，新版本也针对 express oltp、complex oltp、olap、htap、kv 等 5 类场景分别梳理了场景化参数模版，配合部署工具，让初始配置就适合每一种业务类型。此外，新版本还融合了 V4.2.x 系列前序版本的诸多兼容性增强和用户体验改进特性，并合入了TP 类 SQL 的性能改进，致力于满足各类应用场景对产品的诉求。
• 4.3.2BP1 已发布：主要对以下两个功能进行增强：1. 异步任务调度：OceanBase 数据库目前已支持 insert overwrite、insert select、create table as、load data 等多种数据导入命令，来支撑数据实时入库。但实时导入的方式需要在导入过程中等待导入完成，不能中断会话，这在大规模数据导入的场景比较不易用。新版本基于 DBMS_SCHEDULER 提供了异步任务调度能力，用户可通过 submit job、show job status 和 cancel job 等命令实现异步导入任务的创建、状态查询和任务取消。2.SELECT INTO OUTFILE 分区导出：OceanBase 数据库目前已支持通过 SELECT INTO OUTFILE 导出多文件，但尚未支持对数据分区后按分区导出。新版本增加按分区导出能力，以得到更清晰的目录结构。在此基础上还可以将文件目录构造为带分区的外表，通过分区路径裁剪，提高外表的查询效率。
• 4.3.3 已发布：OceanBase V4.3.3 作为 4.3 系列的第一个 GA 版本发布，在几个关键场景完成了突破。一是在关系型数据库基础上支持了适用于 AI 类分析处理的向量类型及索引；二是更好满足 HTAP 混合负载场景下，TP、AP 资源物理强隔离诉求的全新的列存副本形态；三是面向 AP 类查询任务的整体可观的性能提升。除此之外，新增 ARRAY 复杂类型支持、优化 Roaringbitmap 类型计算性能，强化物化视图改写刷新等能力，扩展外表功能、提高外表导入性能，优化 AP 类 SQL 的计划生成和执行策略，加快面向 OLAP 负载的产品化能力提升。新版本还支持了一种只需恢复日志无需恢复数据到本地即可提供读写服务的快速恢复能力，也支持了 QUERY 级别的资源组设定，提升了系统的可靠性和易用性。同时，V4.2.4 及之前版本的大部分特性已经在 V4.3.3 补充支持，后续也会推出同样可应用于 OLTP 业务生产的全新融合版本。
• 4.3.4 已发布：面向 AP 业务的 GA 版本，在第一个 GA 版本 V4.3.3 的基础上，新增多个重要特性。完善多值索引能力，丰富全文索引场景，提升查询性能；完善旁路导入功能，优化主键表写临时文件开销，提高数据导入效率；新增自动分区分裂功能、Format Outline 功能、租户级全局控制导数走旁路导入功能，提升产品易用性；同时对 OBKV 支持全局索引、OBKV-HBase 能力增强等 V4.2.5 及之前版本的大部分特性，进行了补充支持。

OceanBase

• 4.2.1 BP8 Released: Added support for log stream replica management, DBLink specified domain name access, primary and backup tenant role switching verification, primary and backup tenant event display, cursor access after transaction submission, SM3 encryption function, OBKV added response time statistics histogram, OBKV-HBase supports column paging and reverse scanning.
• 4.3.2 Released: OceanBase V4.3.2 is a performance-enhanced version for AP business, with all-round improvements in data reading, data distribution, data calculation, vectorized processing, and plan selection, and an overall improvement of 10%-15% in AP benchmark performance. The introduction of Roaringbitmap data type and related calculation expressions provides a better choice for large data set operations and deduplication scenarios. Enrich the incremental bypass import function, improve the full bypass import performance, expand support for Parquet file appearances, and accelerate the processing speed of large-scale data. As an integrated database, the new version also sorts out scenario-based parameter templates for five scenarios, including express oltp, complex oltp, olap, htap, and kv, and cooperates with deployment tools to make the initial configuration suitable for each business type. In addition, the new version also integrates many compatibility enhancements and user experience improvement features of the previous versions of the V4.2.x series, and incorporates performance improvements for TP-type SQL, dedicated to meeting the product demands of various application scenarios.
• 4.3.2BP1 Released: The following two functions are mainly enhanced: 1. Asynchronous task scheduling: OceanBase database currently supports multiple data import commands such as insert overwrite, insert select, create table as, and load data to support real-time data storage. However, the real-time import method requires waiting for the import to complete during the import process and cannot interrupt the session, which is not easy to use in the scenario of large-scale data import. The new version provides asynchronous task scheduling capabilities based on DBMS_SCHEDULER. Users can use commands such as submit job, show job status, and cancel job to create, query the status, and cancel tasks for asynchronous import tasks. 2. SELECT INTO OUTFILE partition export: OceanBase database currently supports exporting multiple files through SELECT INTO OUTFILE, but does not yet support exporting by partition after partitioning data. The new version adds the ability to export by partition to obtain a clearer directory structure. On this basis, the file directory can also be constructed as a partitioned external table, and the query efficiency of the external table can be improved by partition path clipping.
• 4.3.3 Released: OceanBase Database V4.3.3 is the first General Availability (GA) release in the V4.3 series, offering significant advancements in key areas. It introduces support for vector types and indexes for AI-related analysis and processing, enhancing its core relational database capabilities. Additionally, it implements a new form of columnar replicas, ensuring physical isolation between transaction processing (TP) and analytical processing (AP) resources in hybrid transaction/analytical processing (HTAP) scenarios. This version also boosts the overall performance of AP queries. Furthermore, the update includes support for the complex ARRAY data type, improved computing performance for the RoaringBitmap data type, enhanced query rewriting based on materialized views, extended external table features, better import performance for external tables, and optimized strategies for plan generation and execution of AP SQL statements. These enhancements significantly improve the database's ability to handle online analytical processing (OLAP) workloads. Additionally, the new version offers a quick restore feature, allowing you to restore only logs instead of data to your local server for faster read and write services. It also introduces support for query-level resource groups, enhancing system reliability and usability. Most features from OceanBase Database V4.2.4 and earlier are supported in V4.3.3. An upcoming integrated version will target online transaction processing (OLTP) scenarios.
• 4.3.4 Released: The GA version for AP services adds several important features based on the first GA version V4.3.3. Improve the multi-value indexing capability, enrich the full-text indexing scenarios, and improve the query performance; improve the bypass import function, optimize the temporary file overhead of the primary key table, and improve the data import efficiency; add the automatic partition splitting function, Format Outline function, and tenant-level global control derivative bypass import function to improve product usability; at the same time, supplement support for most of the features of V4.2.5 and previous versions, such as OBKV support for global indexing and OBKV-HBase capability enhancement.
