8。前言XMPP开源IM客户端Spark近日发布了2.8.0版,该版本是个主要更新版本,标志着对
Java 7 的支持已经结束,从 2.8.0 起,在线的安装包在 Java 7
下将不能运行,官方建议升级至 Java
8。Spark是一个开源、跨平台IM客户端(支持Linux、windows、Mac OS
X平台)。它的特性支持集组聊天,电话集成和强大安全性能。如果企业内部部署IM使用Openfire+Spark是最佳的组合。官方的说明原文This
is a major release marking the end of support for Java 7 (which has
reached the end of life state more than a year ago). Full Spark
installers have already been bundled with Java 8 for some time. Online
installer won’t work with Java 7 starting with 2.8.0 version. We
recommend updating to Java 8. Underlying Smack library has been updated
to the latest version in this release. Roar plugin has received new
popup control options as
well.(官方原文:

摘要即时通讯云服务商LeanCloud
2016年8月5日因由于缓存集群超负载崩溃,导致即时通讯服务瘫痪30分钟之久!以下消息来自LeanCloud官方:8
月 5 日晚上 7 点 10 分开始,LeanCloud
中国节点上的某一缓存集群因为流量过大,CPU
资源被占满而停止了服务,从而导致数据存储及依赖它的服务(云引擎、推送、实时聊天)出现约半小时的中断,在此期间有部分应用可能会遇到请求无法完成的情况。详细报告如下。故障节点和影响范围只有中国节点出现了问题,受影响的服务与时间段列举如下,其他服务未受到影响。服务名区域受影响时段范围数据存储中国19:10
– 19:41全部不可用云引擎中国19:10 – 19:41全部不可用实时通信中国19:10 –
19:41部分不可用(消息 hook 功能不可用、离线推送延迟)消息推送中国19:10 –
20:02推送大面积延迟统计服务中国19:10 –
20:23全部不可用(数据收集接口关闭)故障时间线19:10:内部监控报警,确认
redis 异常(CPU 资源占满,失去响应)。19:13:redis
机器无法直接重启,开始尝试逐步关停其他服务(依次是推送、聊天推送、云引擎、统计),以降低请求压力。19:41:redis
集群恢复可用,同时数据存储、云引擎和实时通信三个服务开始恢复。20:02:消息推送服务开始恢复,redis
集群运行正常。20:23:成功为统计服务单独搭建 redis
集群,统计服务的数据收集接口开放,新老 redis
集群运行正常。至此所有服务全部恢复。后续措施将该 redis
集群从业务层面进行拆分,小集群化。将 redis
集群进行高可用架构升级,避免单点故障。对集群加强容灾演练,确保异常条件下服务稳定。对于本次故障,我们诚恳地向您道歉。我们将免掉您账户中全部应用在
8 月 5 日当天的所有费用,以表诚意。
