I was wondering what the status is of the projection feature.
The official documentation says projections are experimental (http://docs.geteventstore.com/server/3.4.0/command-line-arguments/).
At blog post from early 2013 says they are close to ready (https://geteventstore.com/blog/20130212/projections-1-theory/).
Please clarify the status of the projection feature. Are they advised to be used in production?
