Scalability, strict consistency and effective cross-row transactions were a must for such OLTP-like workload. YDB was built by people with strong background in databases and distributed systems, who had an experience of developing No-SQL database and the Map-Reduce system for the one of the largest search engine in the world. +We found that YDB's flexibles design allows us to build more services on top of it including persistent queues and virtual block devices. Basic YDB features: - - Fault-tolerant configuration that survive disk, node, rack or even datacenter outage - - Horizontal scalability - - Automatic disaster recovery with minimum latency disruptions for applications - - Standard SQL for data manipulation and scheme definition - - ACID transactions across multiple nodes and tables with strict consistency + - Fault-tolerant configuration that survive disk, node, rack or even datacenter outage; + - Horizontal scalability; + - Automatic disaster recovery with minimum latency disruptions for applications; + - SQL dialect (YQL) for data manipulation and scheme definition; + - ACID transactions across multiple nodes and tables with strict consistency. ### Fault-tolerant configurations -YDB Platform could be deployed in three different zones.
