decorate: Decorate the slow function to enable caching

In kirillseva/blink: blink (http://github.com/kirillseva/blink)

Description

Decorate the slow function to enable caching

Usage

decorate(fun, salt = NULL, type = "type", id_col = "id",
  strategy = function(...) {     as.data.frame(purrr::map_df(...)) })

Arguments

fun	function. Function to be wrapped around a caching layer.
salt	character. The names of the other parameters to be supplied to the original function that modify the results. For example, in get_movie_details(id = 100, type = 'film', extended_details = TRUE) extended_details set to true might be returning a larger dataframe.
type	character. Type of id, like customer_id, author_id, song_id etc.
id_col	character. The name of the argument to the original function that acts like id.
strategy	function. Execution strategy. Blinck will map over the supplied ids and then intelligently choose whether to pull from cache or compute from scrath. This functions signature is fn(ids, fn), where ids are the ids you've passed in, and fn is the extraction function, that computes/reads individual value from cache. Default is purrr:::map_df
