Internship: High-performance read-heavy local databaseJoin us and shape the future of travel
Shaping the future of travel has always been important to us at Amadeus. Today, with technology getting smarter by the minute, that future is more exciting than ever.
We work at the heart of the global travel industry. Amadeus offers you the opportunity to learn and grow and drive your own progression in an exciting and multicultural environment.
Our people are driven by a passion for 'Where next?' If you want to shape your career and the future of travel, Amadeus is the place for you.
The Data Distribution Frameworks team is a newly created team which inherited from challenging topics as Amadeus is more and more embracing the Cloud. We develop middleware products which are then used by numerous Amadeus application to build their own software. We are responsible for handling the distribution of the middleware data used by all the Amadeus applications. This data has to be made available both inside the existing Amadeus Data Center, and also to remote DCs. We also own the Easy Tables framework, a key-value oriented framework widely used in Amadeus to store Amadeus applications’ configuration and applicative data.
With the Easy Table product, the Data Distribution Frameworks team provides a solution to access common data in very high read throughput and low write throughput manner. A good example of such data are the referential data (worldwide list or airports, worldwide list of countries …). In order to minimize the elapsed time of read access to this data, it is serialized from the main server as a file and then replicated locally on all applications filesystems. Today, this data is stored in SQLite databases. Sqlite is a versatile local database but it is not specifically tailored for high read throughput. There are innovative solution like lmdb or sparkey that could improve our solution.
