  • v2.7.3

    July 19, 2019

    2.7.3

    Compatibility

    ♻️ In order to unify the implementation of service governance rules in different configuration centers, such as Zookeeper, Nacos, Etcd, etc., we have refactored some implementations of the configuration center compared to 2.7.0~2.7.2.

    • ⬆️ For users who are using 2.7.x service governance rules, please check the new implementation before upgrading to 2.7.3, make sure all rules have a copy under the new storage path to ensure a smooth upgrade.
    • ⬆️ For users who have upgraded the 2.7.x version but are not using any service governance rules, you can upgrade directly.
    • 🚀 For users using 2.6.x and lower versions can upgrade directly. But make sure you follow the following instructions Upgrading from 2.6.x to 2.7.x

    🔄 Change List

    👍 Asynchronous support

    • Unified asynchronous and synchronous callback process, exception scenario triggers onError callback, #4401.
    • Performance degradation caused by CompletableFuture.get() in JDK1.8 environment, #4279.

    🔧 Configuration Center

    • ConfigCenter custom namespace does not take effect, #4411
    • Unify the models implemented by several configuration centers such as Zookeeper, Nacos, and Etcd. Please refer to the description for possible incompatibility issues, #4441
    • Adjust Override Coverage Rule Center Priority: Service Level > Application Level, #4175.

    2.6.x compatibility

    • Support Zipkin tracing feature provided by Zipkin officially, #3728, #4471
    • DubboComponentScan supports simultaneous scanning of annotations under the com.alibaba.* and org.apache.* packages, #4330

    🔧 The Nacos Registration Center only subscribes to the address list and no longer subscribes to configuration information, #4454.

    👌 Support to read the environment configuration from the specified location, which can be specified by -D or OS VARIABLE. Please refer to automatically loading environment variables

    🛠 Some other bugfixes, #4346 #4338 #4349 #4377

    升级注意事项

    为了统一不同配置中心(如Zookeeper、Nacos、Etcd等)对于服务治理规则的实现,我们对2.7.0以来的配置中心的部分实现进行了重构。

    • 📄 对于已使用了2.7.x新版本服务治理规则的用户,升级2.7.3之前请先查看新版实现,确保已有规则在新路径下已经存在拷贝,以确保平滑升级。
    • 对于已经升级了2.7.x版本,但是未使用服务治理规则的用户,此次升级不受影响。
    • 🚀 对于2.6.x及以下版本用户不受此次变更影响,升级步骤请参见升级到2.7.x的说明文档

    🔔 Notice

    🚚 'zkclient' extension for 'org.apache.dubbo.remoting.zookeeper.ZookeeperTransporter' is removed from Dubbo 2.7.1, and 'curator' extension becomes the default extension. If you happen to config your application to use 'zkclient' explicitly, pls. switch to use 'curator' instead.

    January 29, 2019

    2.7.0

    Requirements: Java 8+ required

    ⬆️ Please check here for notes and possible compatibility issues for upgrading from 2.6.x or lower to 2.7.0.

    🆕 New Features

    ✨ Enhancement of service governance rules.

    • Enriched Routing Rules.
      1. Conditional Routing. Supports both application-level and service-level conditions.
      2. Tag Routing. Newly introduced to better support traffic isolation, such as grey deployment.
    • Decoupling governance rules with the registry, making it easier to extend. Apollo and Zookeeper are available in this version. Nacos support is on the way...
    • Application-level Dynamic Configuration support.

    - Use YAML as the configuration language, which is more friendly to read and use.

    🔧 Externalized Configuration. Supports reading dubbo.properties hosted in remote centralized configuration center - centralized configuration.

    🔧 Simplified registry URL. With lower Registry memory use and less notification pressure from Service Directory, separates Configuration notification from Service Discovery.

    📇 Metadata Center. A totally new concept since 2.7.0, used to store service metadata including static configuration, service definition, method signature, etc.. By default, Zookeeper and Redis are supported as the backend storage. Will work as the basis of service testing, mock and other service governance features going to be supported in OPS.

    Asynchronous Programming Model (only works for Dubbo protocol now)

    - Asynchronous filter chain callback.

    Serialization Extension: Protobuf.

    Caching Policy Extension: Expiring Cache.

    ✨ Enhancements / Bugfixes

    Load Balancing strategy enhancement: ConsitentHash #2190, LeastActive #2171, Random #2597, RoundRobin #2650.

    ⬆️ Third-party dependency upgrading.

    • Switch default remoting to Netty 4.
    • Switch default Zookeeper client to Curator.

    - Upgrade Jetty to 9.x.

    👍 IPV6 support #2079.

    🐎 Performance tuning, check hanging requests on a closed channel, make them return directly #2185.

    🛠 Fixed the serialization problem of JDK primitive types in Kryo #2178.

    🛠 Fixed the problem of failing to notify Consumer as early as possible after the Provider side deserialization failed #1903.

    ⬆️ Upgrading and Compatibility Notifications

    📚 We have always keep compatibility in mind during the whole process of 2.7.0. We even want old users to upgrade with only on pom version upgrade, but it's hard to achieve that, especially when considering that we have the package renamed in this version, so we had some tradeoffs. If you only used the Dubbo's most basic features, you may have little problems of upgrading, but if you have used some advanced features or have some SPI extensions inside, you'd better read the upgrade notifications carefully. The compatibility issues can be classified into the following 5 categories, for each part, you can find the detailed dos and don'ts in this documentation.

    Interoperability between 2.7.0 and lower versions

    📦 Package renaming

    com.alibaba.dubbo -> org.apache.dubbo

    Simplification of registered URLs

    Service Governance Rules

    🔧 Configuration

    环境要求:需要Java 8及以上版本支持

    🆕 New Features

    服务治理规则增强。

    • 更丰富的服务治理规则,新增应用级别条件路由Tag路由
    • 治理规则与注册中心解耦,增加对Apollo等第三方专业配置中心的支持,更易于扩展
    • 新增应用级别的动态配置规则

    - 规则体使用更易读、易用YAML格式

    🔧 外部化配置。支持读取托管在远程的集中式配置中心的dubbo.properties,实现应用配置的集中式管控。

    📄 更精炼的注册中心URL,进一步减轻注册中心存储和同步压力,初步实现地址和配置的职责分离。

    📇 新增服务元数据中心,负责存储包括服务静态化配置、服务定义(如方法签名)等数据,默认提供Zookeeper, Redis支持。此功能也是OPS实现服务测试、Mock等治理能力的基础。

    异步编程模式增强(限定于Dubbo协议)

    - 异步Filter链

    新增Protobuf序列化协议扩展

    新增ExpiringCache缓存策略扩展

    ✨ Enhancements / Bugfixes

    负载均衡策略优化,包括ConsitentHash(#2190) 、LeastActive(#2171)、Random(#2597) 、RoundRobin(#2586) (#2650)

    升级第三方依赖:默认通信框架为netty 4、默认ZK客户端为Curator、Jetty 9k

    增加地址读取时对IPV6的支持(#2079)

    性能优化,链接关闭的情况下使得Consumer快速返回 (#2185)

    修复Jdk原生类型在kryo中的序列化问题 (#2178)

    修复Provider端反序列化失败后,没有及早通知Consumer端的问题 (#1903)

    升级与兼容性

    📦 此次版本发布我们遵循了保持和老版本兼容的原则,尤其是在保证与低版本互操作性的问题上,2.7.0版本是能做到完全兼容的。对于2.7.0的默认行为,最容易带来兼容性问题的此次发布版本内容中的package重命名,但这类问题是显示的,即能在升级后的编译期发现并予以解决。了解更多升级和兼容性注意事项
