2 features not sure if it's in cloudflare worker's roadmap

  1. faceted search (elastic search) kind of serverless function / feature
  2. increment by +1 / +N type of KV storage for immediate updates of values as site statistic counter.

because these two, i need to deploy other services to go along with cloudflare workers. these are the only 2 things that’s giving me a lot of headaches in terms of integration

No idea on #1, there’s no public feature roadmap.

For #2, we also don’t know if they’re working on it, but there is a feature request at Support increment/decrement operations (atomic counters) in Workers KV you should vote on.
