XtremeData dbX is a full SQL and ACID compliant database engine based on shared-nothing, massive parallel query execution. The underlying technology relies on PostgreSQL (similarly to AWS Redshift). In essence, the key architecture components are the head node and multiple data nodes – this is a fairly common patterns in massive parallel execution scenarios.
The head node manages the client connections, parses and plans the queries and sends the result back to the clients. The data nodes manage data storage and execute queries.
