Class Method Details

.load_on_late_setup ⇒ Object

This loads the pro components into memory in case someone required karafka-web prior to the license usage. This can happen for users with complex require flows, where Karafka license is not part of the standard flow

In such cases Web may not notice that Karafka should operate in a Pro mode when it is being required via Zeitwerk. In such cases we load Pro components prior to the setup.
