Fydb is a distributed in-memory no-SQL DB. It supports distributed deployment, and can integrate heterogeneous data sources. Data of FyDB is stroed in memory as key-value structure, and it is also persistent. According to No-SQL theories, FyDB discarded support on Data Integration to gain better performance and high availability, which means it will not check integration of Parent-Children data. While Data Integration is one of the most important features of traditional relationship database.
