App metrics

Relevant for some use cases: Since runtime version 4.85.0 journey.profiling can be enabled for an app which makes performance profiling in Chrome a lot simpler for developers. This includes:

  • Logging all queries and view functions together with their duration.
  • Adding info on the sync system overhead and digest cycles.
  • Adding info on index usage which makes it easier to see which queries can be optimized, versus running explain() individually on queries.
  • Making it possible to enable this profiling in production environments, not just testing.
