I created a simple realtime spec to use with Kafka, and I want to add some more dimensions and metrics to it. However, I’d also like to preserve the data I collected with it. I haven’t seen any guides to doing this, but since the structure of the data is defined by the spec, I would assume that all I have to do is update the spec’s JSON.
Are there any risks to updating the spec’s dimension/metric fields? Should I expect to have to somehow backfill the data for either of these?
