Apache Storm 分布式实时计算系统

Apache Storm 的前身是 Twitter Storm 平台,目前已经归于 Apache 基金会管辖。Apache Storm 是一个免费开源的分布式实时计算系统。简化了流数据的可靠处理,像 Hadoop 一样实现实时批处理。Storm 很简单,可用于任意编程语言。Apache Storm 采用 Clojure 开发。


Apache Storm 0.10.0 发布,此版本是个稳定版本,相比之前的 Beta 版本主要包括 bug 修复和改进:

  • STORM-1108: Fix NPE in simulated time

  • STORM-1106: Netty should not limit attempts to reconnect

  • STORM-977: Incorrect signal (-9) when as-user is true

  • STORM-843: [storm-redis] Add Javadoc to storm-redis

  • STORM-866: Use storm.log.dir instead of storm.home in log4j2 config

  • STORM-810: PartitionManager in storm-kafka should commit latest offset before close

  • STORM-928: Add sources->streams->fields map to Multi-Lang Handshake

  • STORM-945:  element is not a policy,and should not be putted in the  element.

  • STORM-857: create logs metadata dir when running securely

  • STORM-793: Made change to logviewer.clj in order to remove the invalid http 500 response

  • STORM-139: hashCode does not work for byte[]

  • STORM-860: UI: while topology is transitioned to killed, "Activate" button is enabled but not functioning

  • STORM-966: ConfigValidation.DoubleValidator doesn't really validate whether the type of the object is a double

  • STORM-996: netty-unit-tests/test-batch demonstrates out-of-order delivery

  • STORM-1056: allow supervisor log filename to be configurable via ENV variable

  • STORM-1051: Netty Client.java's flushMessages produces a NullPointerException

Apache Storm 的前身是 Twitter Storm 平台,目前已经归于 Apache 基金会管辖。

Apache Storm 是一个免费开源的分布式实时计算系统。简化了流数据的可靠处理,像 Hadoop 一样实现实时批处理。Storm 很简单,可用于任意编程语言。Apache Storm 采用 Clojure 开发。

Storm 有很多应用场景,包括实时数据分析、联机学习、持续计算、分布式 RPC、ETL 等。Storm 速度非常快,一个测试在单节点上实现每秒一百万的组处理。

目前已经有包括阿里百度在内的数家大型互联网公司在使用该平台。
