I am trying out the index task using some CSV that are present. I wanted to know a few things
- Inside dataSchema -> parser -> parseSpec we have the following 2 properties. Is there any difference between the two or will be the same always?
- dimensionsSpec -> dimensions
- If I want to add a aggregation column count while indexing my understanding is that it should go inside metricsSpec. But do I need to add it somewhere else also?
