YDB: scalable fault-tolerant NewSQL DBMS from Yandex. Now open source
April 19, 2022. Yandex has published the source code of the distributed NewSQL DBMS YDB, which allows you to create scalable, fault-tolerant services that can support a large operational load. The code is available under the Apache 2.0 license.
YDB is an open-source Distributed SQL Database that combines high availability and scalability with strict consistency and ACID transactions. YDB observes the occurrence of occurrences and recovery in the event of occurrences from the formation or even the occurrence of the center of the day. The reliability of YDB has been tested on Yandex services (Alisa, Taxi, Market, Metrika and almost 500 more projects). You can deploy YDB both at will and on external servers, including Yandex Cloud or providers.
