Detailed Explanation of System Projections

Hi, Regarding the system projections, I’ve re-read the documentation a few times and I’ve got a couple of questions :slight_smile:

  1. As per this question - what is the clear difference between stream by category and by category?

  2. What would the $streams projection actually be used for, an example would help please!

  3. $by_correlation_id, much the same as above, i think i’m missing something obvious here?

I think that the documentation on the site is a good start, but a work through with examples in more places would allow people to read it and realise what you can can actually fully achieve with the Event Store user projections.


Thanks Ross, this is coming slowly… But in the meantime, if you have insights to share, PRs are always welcome :slight_smile:
