Caching callbacks

Open cpsievert opened this issue 7 years ago • 2 comments

  • [ ] Implement

    • https://github.com/ropensci/drake seems like a promising solution to handle more than just pure functions
    • If drake doesn't pan out, use https://github.com/r-lib/memoise
    • Could more be done to support this in dash-renderer (i.e., keep a hash table of md5 sums of R/python objects)?

  • [ ] Document a complement to https://plot.ly/dash/performance

@alexcjohnson Is this something that should be on the roadmap once hot reloading and index customization have been implemented?

Interesting idea to build support for this into renderer - it would need to be opt-in for each callback that knows caching is OK, but I can see it being a big help in certain cases. If you want to make an issue in the main dash repo for this feel free.

Other than that, I don't think we want to build this functionality into the back end for now. Figuring out the R equivalent of https://plot.ly/dash/performance would be nice though.
