EdgeDB

EdgeDB is a graph-relational database that aims to solve design problems posed by relational models such as relational models such as object–relational impedance. Tables are defined as object types with links representing dependencies between tables.

It is paired with its own query language EdgeQL, that provides composable queries (that are compiled into optimized SQL) and a simplified interface for database development. EdgeDB is powered by PostgreSQL in the backend and thus inherits its ACID compliance, reliability, and performance.

Data Model

Object-Relational

Edge DB describes itself as a "graph-relational" database that inherits many characters from a relational DBMS. Data is represented as strongly-typed objects which are the equivalent of tuples in a relational DBMS. Each object is link with an immutable id, thus not requiring an extra column for uniqueness.

Isolation Levels

Serializable

EdgeDB only supports serializable isolation. There is currently no plan to support other isolation levels, as their internal tests indicate very little performance gains.

Query Execution

Tuple-at-a-Time Model

EdgeDB uses PostgreSQL as its query execution engine and so supports the same tuple-at-a-time model as PostgresSQL.
