Virtual query

Datasets in data.world are built off of the connections, but no data is stored in them. When a user performs a data query, a short-lived connection fetches only the query results. These results are NOT persisted--neither in storage nor in memory. Additionally, by default, queries have a 5 minute timeout for performance and security reasons. Finally, all queries are comprehensively tracked and audited via query audit logs that customers can access and monitor.

A virtual appliance (or optionally a hardware appliance or reverse SSH tunnel service) is implemented in the customer environment by the customer. The virtual and hardware appliances are powered by our partner Trustgrid, a secure connection bridge technology vendor trusted by many of the largest banks and financial institutions. Using the Trustgrid technology, a network bridge is configured on the data.world side in conjunction with the customer. At that point, read-only system user credentials can be securely stored in data.world as connections, and encrypted connections are initiated as outbound only. Connections in the system are encrypted and initiated as outbound only.
