Stream Inspector - Allows you to peek at the data as it enters Conduit via source connectors and as it travels the destination connectors. This is critical when trying to debug what has gone wrong with your pipeline.
Dead Letter Queues - You are now able to save data that has failed to be processed by sending the message to another connector to be saved and used again once you debug your error.
Connector Parameter Validation - Conduit connectors may require several parameters or data types in order to successfully connect to data stores. With Connector Parameter Validation Conduit will surface the correct error message to the end user. This allows for transparency and improves the connector setup process.
And much more!
