Azure Data Factory to Collibra Integration - Collibra Marketplace

in our research a few months back, Azure Data Factory (ADF) had a C# interface that is published by Microsoft on NuGet. The connector documentation for your new connector has a distinctively Java (Springboot) flavor to it (which impressed me). Is there a Java interface to ADF now? What library(ies) does your connector use to communicate with ADF please?
