1. Is Python code base supported in Matillion for any future extensions to be done to the connector code? Lets say, I want to add a new&nbsp;datasource support and want to achieve this programmatically. Is this possible or any limitations?

&nbsp;

2. Is the point #1 achievable using code only and NO UI?

&nbsp;

3. Is there any Authentication Mechanism in Matillion and if yes then how we can use that?

&nbsp;

4. What are different sync modes supported? We are interested more on the incremental load (once the full refresh/load is done initially). Is it column based?

&nbsp;

5. Is Metadata there, if for example we are using Salesforce data source which have multiple tables and user wants to select few columns or rows of his/her choice then will Metadata will come with it or not?

&nbsp;

6. Please could you elaborate more on the cost consideration as per the volume of data - as well as performance. Any challenges here?

Those are some really broad questions. I would recommend going one by one and searching here in the forums for answers. It's difficult to answer since your questions are very broad.

If you are a Matillion user, another way is to set up sample projects and test out your scenarios.

That way you can answer your questions for yourself. 👍
