===============================

Speaker: Jean Armel Luce

Jean Armel is a Senior Software Engineer at Orange, with more than 20 years of software development in various environments. During the last years, he has had to deal with some applications using large databases that require scalability and high availability. A few years ago, Jean Armel had learned about NoSQL and did a large study about a few NoSQL databases (Cassandra, MongoDB, HBase, Hypertable, Riak, …). This study focused on performances, robustness, scalability and exploitability.

At the end of his study, Orange decided to replace the relational databases (Postgres and Mysql cluster) with Apache Cassandra for the application PnS (a highly available and critical service for collecting and serving live data about Orange customers), in order to sustain growth in requests and volume of data.

The migration to Cassandra was done in 2013, and all the PnS data are now stored in the C* cluster.

Topics:

- Short description of the application PnS. Why did we choose C* for this application ?

o Short description of the application PnS

o Why C* fits better our requirements than the other databases ?

- The results after the migration … (and some hardware considerations)

o Performance

o Robustness

o Scalability

- Analytics with Hadoop/Hive over Cassandra

o The architecture of the ring

o How we did the isolation between the on line queries and the map/reduce processes ?

- Our feedback after more than 1 year in production

o Feedback from the developers

o Feedbacks from the exploitation team

o Feedbacks from our customers
