Cassandra Сonf is over in Yekaterinburg
On December 9, the first conference in Russia dedicated to the NoSQL-system Cassandra was held in Yekaterinburg. The conference was organized by IT-People, SKB Kontur and DataStax. The event was supported by the Ministry of Transport and Communications of the Sverdlovsk Region.
The idea of the conference was to gather all developers interested in Cassandra in Russia and provide them with a place for communication and exchange of experience. In addition, we invited foreign speakers to speak at Cassandra’s first-hand development plans from DataStax committers and listen to one of the most famous projects working for Cassandra from a representative of Spotify.
As a result, 150 participants from all over Russia came to the conference to discuss Cassandra. Listeners came from Moscow, St. Petersburg, Omsk, Chelyabinsk. 16 speakers from Russia, USA, England, Sweden, Ukraine, Latvia spoke.

The conference turned out to be rich: presentations in English and Russian, streams for experienced and beginners, general presentations from foreign speakers, Lightning Talks.
One of the ideologues of Cassandra Jonathan Ellis from Datastax began the conference. A visitor from Texas talked about how Cassandra is used in Adobe, eBay, Instagram and Spotify, and why Cassandra is one of the leading NoSQL systems.
After him, a spokesman for Spotify Axel Liljencrantz spoke about the details of working with Cassandra.
Ruth Stryker from DataStax gave an introductory talk about CQL and DataStax Java.
After that, the participants divided into two streams and went to listen to the reports, depending on the level of their knowledge of Cassandra. Oleg Anastasyev from Odnoklassniki was the first to perform in the stream for the experienced ones. Oleg told about the unusual use of Cassandra in Odnoklassniki: what is unusual, what this approach allowed to do, and what all this led to.
Olga Sobolev, Kirill Ivanov and Ivan Burmistrov from SKB Kontur told about their experience of using Cassandra: about the service model, which was closely integrated with Cassandra, and how the task of saving and retrieving objects in chronological order was solved in the Contour.
On December 8, an article titled “The largest torrent trackers hit the Kaspersky Lab's parental control database” appeared on Habrahabr. All day, habrovchane wondered: by what algorithms does this very robot work and why torrents got into the “base of non-children's sites”. The participants of assandra Conf had a happy opportunity to listen to how it turned out and how this very robot from the mouth of the developer of Kaspersky Lab Alexander Sabinin works.
In the parallel hall were reports for beginners. Evgeny Tikhonov from the SKB Kontur gave an introductory report to Cassandra. Maxim Sychev and Alexander Kokovin talked about why SKB Kontur decided to replace its storage system and chose Cassandra. Evgeny Kuprylyansky from SKB Kontur made a report about indexing data from Cassandra into SQL-storage. Alexander Solovyov told about the use of Cassandra in e-commerce.
After this, the threads re-merged for general reports. Alexey Yeshchenko from DataStax told about time series, collections, secondary indexes, CAS and user types.
Nikolai Alimenkov from ZoralLabs presented in the report a solution that they developed for one of the products, in which all data is stored in Cassandra. The decision has acquired many useful qualities, about which Nikolai told.
Lightning Talks conference ended.
Each expert tried to make his presentation interesting and useful, and each report aroused genuine interest of the audience - questions rained on the speakers not only after the speech itself, but also during the breaks. It was possible to personally communicate with each of the speakers during coffee breaks, lunch and afterparty, which foreign guests enjoyed attending. Backstage communication was decorated with traditional fruits from IT-People and holiday souvenir mugs for each participant from SKB Kontur.
