Hello, is there any timeline on when this could make it into the provider? Would love to have this soon!

[dgomez04]

Hi @ian-norris-ncino. I'm aiming to have this integrated into the provider by the end of the month, depending on my availability. I'll keep you posted.

It could be easier for people to specify input_param as separate blocks, like we do in other resources

[alexott]

Although doc says that input_params is a block, and then there are parameters inside: https://docs.databricks.com/api/workspace/functions/create#input_params
