backend-impala: Backend: Impala
In dbplyr: A 'dplyr' Back End for Databases
backend-impala R Documentation
Backend: Impala
Description
See vignette("translation-function") and vignette("translation-verb") for
details of overall translation technology. Key differences for this backend
are a scattering of custom translations provided by users, mostly focussed
on bitwise operations.
Use simulate_impala() with lazy_frame() to see simulated SQL without
converting to live access database.
Usage
simulate_impala()
Examples
library(dplyr, warn.conflicts = FALSE)
lf <- lazy_frame(a = TRUE, b = 1, c = 2, d = "z", con = simulate_impala())
lf %>% transmute(X = bitwNot(bitwOr(b, c)))
