alibaba / oceanbase Goto Github PK

没有binlog，请问如何做数据订阅同步？

想要将数据库从MYSQL和ORACLE 切换到OceanBase 但在使用中发现开源版本不支持自定义函数与存储过程（存储过程用的倒是不多），期待开源版本能支持自定义函数与存储过程

和传统数据库比，oceanbase是因为没有刷新脏页的机制才避免了随机写的消耗吗

还会放在这个repo里面吗？

OceanBase history

In 2010, OceanBase team leader Zhenkun Yang joined Alibaba. Because of the increasing concurrency in Alibaba's business and the shortened development cycle to build a database for new transaction, Yang found that original DBMS can't support for rapidly growing workloads in Alibaba. He decided to abandon the traditional DBMS framework and develop a novel DBMS from scratch. At the very beginning, he presented three kernel principles for their new products: (1) distributed (2) low cost (3) high reliability.
In 2013, Alipay decided to stop using Oracle. Since the alternate choice MySQL can't ensure strong consistency between active server and standby server, OceanBase got its first opportunity. From now on, OceanBase is not open sourced anymore.
From 2014 to 2016, this team spent three years developing OceanBase 1.0. It is the first commercial DBMS which supports distributed transactions.
From 2017, OceanBase started to serve for external customers.
In 2019, OceanBase beat Oracle and won the first place in TPC-C test.

能提供这篇文章 (OceanBase的正确使用方法) 里描述的 ObGroupDataSource 所属的包的地址吗?

这篇文章Java 连接 OceanBase 示例 所提供的驱动包 oceanbase-client 里只有简单的 Driver 没有 DataSource。

或者能提供这篇文章(ApsaraDB For OceanBase Writer)里描述的 OceanBase-connector-java 的 maven 仓库地址或者对应 jar 的下载地址吗(如果这个里面有对应 DataSource 类的话)?

在写sql脚本时，使用'--'作为注释，没有被识别，执行脚本里，会把'--'识别为脚本内容导致报错；
在使用#作为注释符的时候，不报错。
