Thanks for the clarification Mike, my bad on that one - the details were hazy but yes, it’s tomcat 8 support that’s the sticking point, & our planned deprecation of batch is the real consideration as to why we’re not evolving the Clojure collector to handle this.
@wege_philip I don’t know of a specific upgrade guide, but Dilyan’s comment here might be helpful for general strategy (it’s for GCP but same principles apply).
Also maybe it makes sense to put that information into the wiki (Setting up a Collector · snowplow/snowplow Wiki · GitHub) so that people won’t start setting up Clojure anymore.
Good point, I’ll raise this, thanks for pointing that out!
