场景介绍

电商平台则需要每天统计各平台的实时访问数据量、订单数、访问人数等等指标，从而能够在显示大屏等展示指标实时变化。

使用DLI Flink SQL配合DMS Kafka、RDS MySQL以及DLV等华为云原生服务，可以简单高效地完成电商业务实时数据的接入、处理、存储与展示。

华为云解决方案优势

1.高吞吐低时延：采用Apache Flink的Dataflow模型，完全的实时计算框架。采用高性能计算资源，单CPU每秒吞吐1千~2万条消息；

2.跨源分析：支持云上多种数据源，数据无需搬迁，即可实现对多个数据源进行分析处理；

3.弹性资源：根据业务实时负载，对计算资源进行动态预估和自动扩缩容；支持多版本Flink，支持用户自定义镜像。

场景介绍

云搜索服务CSS可用于全场景日志分析，包括ELB日志、服务器日志、容器和应用日志。其中Kafka作为消息缓冲队列，用于削峰填谷，Logstash负责数据ETL，Elasticsearch负责数据检索与分析，最后由Kibana以可视化的方式呈现给用户。

华为云解决方案优势

1.采用鲲鹏算力、冷热分离、存算分离，成本同比降低30%+；

2.支持丰富的可视化查询语句与拖拽式报表；

3.支持每天百TB级数量入库，提供PB级以上数据处理能力。

场景介绍

电商、物流企业有订单查询业务场景，数据量大、查询并发高、吞吐大、且要求查询延迟低。关系型数据库具备较好的事务性与原子性，但其TP与AP处理能力较弱，通过将CSS作为备数据库，可提升整个系统的TP与AP处理能力。

华为云解决方案优势

1.支持文本、时间、数字、空间等数据类型；亿级数据查询毫秒级响应；

2.支持200+数据节点，支持1000+个数据字段；

3.规格变更、配置更新采用滚动重启，双副本场景下业务0中断。

场景介绍

应用的数据（如：注册信息）存在关系型数据库中，想对数据库内的数据进行分析，遇到难题：

1.数据量日益增多，复杂查询关系型数据库查不出来；

2.数据分库分表存在多个关系型数据库中，无法做全量分析；

3.不想因为分析业务影响在线业务。

华为云解决方案优势

熟悉的SQL体验：DLI的SQL语法全兼容关系型数据库的标准ANSI SQL 2003

0学习成本，使用习惯保持一致

极致性能：DLI采用分布式内存计算模型，轻松处理海量数据
