This repository is dedicated solely to protocol documentation and does not provide any WebSocket drivers or driver support. However, it includes some implementation examples and a list of officially supported drivers at the bottom of the page.
The JSON over WebSockets client-server protocol allows customers to implement their own drivers for all kinds of platforms using a connection-based web protocol.
The main advantages are performance improvements from lock-free metadata calls, flexibility regarding the programming languages you want to integrate Exasol into, and a more native access compared to the standardized ways of communicating with a database, such as JDBC, ODBC or ADO.NET, which are mostly old and static standards and create additional complexity due to the necessary driver managers.
