We have about 100 time series we want to use, along with some new ones that might be created by analysts. How should we think about this, create 100 individual assets and all new ones needs to be defined in code as well sounds like the correct approach. But is there another way or methodology i am missing?
And yes, they do need to be defined in the code. What you can do is have some config file, read that config file that specifies your asset locations, and create an asset through an asset factory
