Hi Fabian, I read about the process function and it seems a perfect fit for my requirement. Although while reading more about queryable-state I found that its not meant to do lookups within job (Your comment in the following link).

I was hoping this to be possible but it seems not to be the case, can you shed some light and if possible recommend some alternatives?
