DolphinDB V3.00.4 solve this with a unified multi-asset data model that treats all financial instruments as standardized, strongly typed computational objects.
Starting from DolphinDB V3.00.4, the cross-database federated query feature simplifies all of this into one idea: don't move the data—query it wherever it is, using a single SQL statement.
Beginning with version 3.00.4, DolphinDB introduces Streaming SQL —a transformative solution to these challenges. Register your business SQL once (with full support for joins, filters, sorting, and aggregations), and the engine automatically tracks changes in underlying data, pushing the latest results in real time to all subscribed clients.
DolphinDB 2.00.18 and 3.00.5 are now officially released!
