User behavior collection platform
Data warehouse concept
Data warehouse (Data Warehouse ) Is owned by the enterprise Decision making The process , Provide a strategic set of all system data
Through the analysis of data in the data warehouse , Can help enterprises , Improve business 、 Control the cost 、 Improve product quality, etc .
Data warehouse , It's not the ultimate destination of the data , It's about preparing for the final destination of the data .
These preparations include the... Of the data :
- cleaning
- escape
- classification
- restructuring
- Merge
- Split
- Statistics
Project requirements and architecture design
Project requirements analysis
Project requirements :
- user Behavior Build data acquisition platform
- Business Build data acquisition platform
- Data warehouse Dimensional modeling
- analysis , equipment 、 members 、 goods 、 region 、 Activities and other core themes of e-commerce , The statistical report indicators are close to 100 individual
- use Ad hoc inquiry Tools , Index analysis at any time
- Monitor cluster performance , An exception needs to be reported to the police
- Metadata management
- Quality monitoring
The project framework
Technology selection
Data acquisition and transmission :Flume,DataX , Maxwell , Kafka , Sqoop
data storage :MySql ,HDFS,HBase,Redis , MongoDB
Data calculation :Hive,Spark,Flink , Tez , Strom
Data query :Presto,Kylin,Impala , DataX
Data visualization :Superset , QuickBI , DataV
Task scheduling :DolphinScheduler、Azkaban、Oozie
Cluster monitoring :Zabbix
Metadata management :Atlas
System data flow design
Business interaction data : Login generated in business process 、 Order 、 user 、 goods 、 Payment and other relevant data , Usually stored in DB in , Such as : Mysql、Oracle
Embedded user behavior data : When users use the product , Data generated during interaction with client products , Such as : Page view 、 Click on 、 Stop 、 Comment on 、 give the thumbs-up 、 Collection
Frame version selection
Apache: Operation and maintenance is troublesome , Compatibility between components needs to be investigated by yourself .( Generally used in large factories , Strong technical strength , There are professional operation and maintenance personnel )( It is recommended to use )
CDH:: The most used version in China , but CM Not open source , There will be a charge this year , A node 1 Ten thousand dollars
HDP: Open source , It can be redeveloped , But no CDH Stable , Less used in China
product | edition |
---|---|
Java | 1.8 |
Hadoop | 3.1.3 |
Hive | 3.1.2 |
Flume | 1.9.0 |
Zookeeper | 3.5.7 |
Kafka | 2.4.1 |
DataX | 3.0 |
Maxwell | 1.29.2 |
Frame selection try not to choose the latest frame , Choose the stable version of the latest framework about half a year ago
Server selection
The physical machine :
- With 128G Memory ,20 Nuclear physics CPU,40 Threads ,8THDD and 2TSSD Hard disk , Dell brand single unit quotation 4W Head start . General physical machine life 5 About years ago
- Need professional operation and maintenance personnel , On average, one month 1 ten thousand . Electricity is also a lot of expenses
Virtual machine :
- Take Alibaba cloud for example , Almost the same configuration , Every year, 5W, The main disk is expensive
- A lot of operation and maintenance work is done by Alibaba cloud , Operation and maintenance is relatively easy
Enterprise selection :
- Companies with financial wealth that have no direct conflict with Alibaba choose Alibaba cloud
- Small and medium companies 、 In order to finance the listing , Choose alicloud , Buy physics machine after pulling down financing
- Have a long-term plan , The funds are quite sufficient , Choose the physical machine
Cluster resource planning and design
( hypothesis : Every server 8T disk ,128G Memory )
- Daily active users 100 ten thousand , Each person has an average of 100 strip :100 ten thousand * 100 strip = 1 Billion bars
- Every log 1K about , Every day 1 Billion bars :100000000 / 1024 / 1024 = about 100G
- We will not expand the server capacity within half a year :100G * 180 God = about 18T
- preservation 3 copy :18T * 3 = 54T
- reserve 20% 30%Buf = 54T / 0.7 = 77T
about 8T * 10 Servers
