MySQL

Technical solutions : 2 new internal productsScala-centric, Play! framework

Cross-channel messaging systemEmail, Mobile, SocialFlexible content managementFlexible targeting of recipientsContent testing strategies : A/B, multivariateEvent-driven : web app events, mobile events, ad hoc eventsAutomation, scheduling, frequency capping

Analytics Data visualization : based on Javascript D3.js, processing.js etc.Tabular Reports, OLAP navigationPluggable alerts : business activity monitoring

A common requirement : scalability!!!Viadeo data is BigProcessing performance is not an option, it is mandatory

Technical solutions : a new architecturebased on CQRS pattern

Technical solutions : a new architecture

• Master dataset : • Historical data stored in HBase• Provided as a service by architects team

• Datamarts : • Built on HDFS using MapReduce jobs• MapReduce eased by use of Cascading library

and Scala DSL (Scalding) • Pushed to in-memory distributed storage• Elastic Search, Riak

Technical solutions : A better architecture

MySQLSQ

OOP

Conclusion

• Many scalable data storage solutions• Rapid application development frameworks and low-risk

programming languages on the JVM• Custom analytics = what we implement is what we use

• Analytical needs are very well identified• Blend data stream and batch processing to answer

different needs• Pluggable Data mining R&D• Analytics for Viadeo members/recruiters/companies :

Social Media Monitoring as a Complex Event Processing topic
