In order to improve the first draft of ERK project, I would like to get some feedback from you.

What features are you missing/you think it may be improved in rsyslog?

Please, try to be as more clear/self-explanatory/simple as you can for better understanding.

* logstash memory footprint is quite high compared to rsyslog,
  although both "doing the same".

that's not something to fix in rsyslog :-)

* rsyslog configuration can't be reloaded live

true

* dynamic variables (calculated on each message processing) aren't
  supported on templates

false. that's what templates do. You can use any variable in a template.

* combine multiple variables into one to build a "date" field isn't
  possible

you can combine variables to form a string that looks like a date in the output, but you can't take arbitrary date parts in a log message and parse them into a real timestamp field that would let you output it in different formats.
