"杭州spark meetup PPT资料--2014-08-31,主要讨论了在电信场景下如何利用Spark构建一站式分析平台,涵盖了电信大数据的关键技术和具体应用案例。" 在2014年8月31日的杭州Spark Meetup活动中,演讲者夏命榛分享了电信行业中Spark技术的应用,构建了一个能够应对各种分析需求的一站式平台。该平台的核心在于利用Spark的强大处理能力,解决电信大数据的实时分析和存储问题。 在电信大数据场景中,一个关键的应用是实时KPI(关键性能指标)计算。当前的系统能够以15分钟的间隔生成KPI报表,但通过Spark可以优化这一过程,实现秒级甚至毫秒级的KPI更新,从而提高决策效率。此外,Spark还用于处理来自探针的实时上报事件,进行详单查询和仪表盘展示,满足从分钟到小时,再到天级的各类报表需求。 在数据模型方面,Spark处理的详单数据经过过滤生成,用于实时KPI计算和复杂事件处理(CEP)。这些数据模型支持对用户行为的快速响应,例如通过实时KPI报表优化服务。HDFS(Hadoop分布式文件系统)在数据入库和高性能实时流处理上面临挑战,而Spark作为更高效的计算框架,能够有效缓解这些问题。 此外,平台展示了多种基于位置的应用。区域人数分布热力图和区域流量分布热力图提供了对人口流动和流量使用情况的深入洞察,有助于城市规划、广告策略制定和网络优化。通过用户相似度计算,可以进行个性化套餐推荐,提升运营商的销售业绩。这涉及到基于用户上网流量的协同推荐算法,以挖掘潜在的商业价值。 电信行业的核心数据资产包括用户ID、网络交互和移动位置,这些数据共同构成了用户的“数字足迹”。通过对这些数据的深度分析,可以构建用户、网络和社会的数字化映射,推动精准营销、道路规划、灾难救援、店铺选址等多个领域的创新应用。 在演示部分,数据显示每天有超过12亿条位置记录,对应80GB的数据量,这强调了大数据处理的规模和复杂性。通过Spark的实时监控和数据关联分析,可以实现对用户行为的深入洞察,进一步优化业务策略,促进电信行业的智能化和精细化管理。

The OpenStack Foundation supported the creation of this book with plane tickets to Austin, lodging (including one adventurous evening without power after a windstorm), and delicious food. For about USD $10,000, we could collaborate intensively for a week in the same room at the Rackspace Austin office. The authors are all members of the OpenStack Foundation, which you can join. Go to the Foundation web site. We want to acknowledge our excellent host Rackers at Rackspace in Austin: Emma Richards of Rackspace Guest Relations took excellent care of our lunch orders and even set aside a pile of sticky notes that had fallen off the walls. Betsy Hagemeier, a Fanatical Executive Assistant, took care of a room reshuffle and helped us settle in for the week. The Real Estate team at Rackspace in Austin, also known as “The Victors,” were super responsive. Adam Powell in Racker IT supplied us with bandwidth each day and second monitors for those of us needing more screens. On Wednesday night we had a fun happy hour with the Austin OpenStack Meetup group and Racker Katie Schmidt took great care of our group. We also had some excellent input from outside of the room: Tim Bell from CERN gave us feedback on the outline before we started and reviewed it mid-week. Sébastien Han has written excellent blogs and generously gave his permission for re-use. Oisin Feeley read it, made some edits, and provided emailed feedback right when we asked. Inside the book sprint room with us each day was our book sprint facilitator Adam Hyde. Without his tireless support and encouragement, we would have thought a book of this scope was impossible in five days. Adam has proven the book sprint method effectively again and again. He creates both tools and faith in collaborative authoring at www.booksprints.net. We couldn’t have pulled it off without so much supportive help and encouragement.
