What's new in Arana v0.2.0

[Yuan Chuang Conference Preview] 1024 Programmers’ Day (two days before), meet at the Open Source China office, let’s talk about AI! >>>

AranaPositioned as a cloud-native database proxy, it can be sidecardeployed as a database service grid in mode. The project address is https://github.com/arana-db/arana . Arana provides transparent data access capabilities. When users use it, they do not need to worry about the "sharding" details of the database and can MySQLuse it just like a stand-alone database Arana.

In this crisp autumn season, Aranathe community is happy to announce that after more than a year of hard work by 47 community contributors, we have officially released 0.2.0the version. This version not only does a lot of optimization work, fixes some bug, but also introduces a number of new features. These new functions include the configuration center supporting watchmechanism to dynamically monitor configuration changes, supporting a visual adminconfiguration management background, shardingfurther enhancing the capabilities of database tables, supporting richer DDLstatements, and supporting shadow table features to facilitate database stress testing. These capabilities will It will provide users with a more stable and efficient experience.

With 0.2.0the release of the version, the functional features of the Aranacommunity 0.3.0version have been planned. In 0.3.0the version, we have planned the following major features:

1. Realize the ability to cross database instances joinand improve the connection query capabilities between different database tables;
2. Implement XAdistributed transaction capabilities based on
3. Implement shardingless capabilities, shield the details of sub-databases and tables from upper-level users, and reduce user learning and usage costs.

The above are 0.3.0the new features planned in , so stay tuned.
