metis.tidy
Access and Query Amazon Athena via the Tidyverse
Description
Methods are provided to use the ‘metis’ JDBC/DBI interface via the Tidyverse (e.g. ‘dbplyr’/‘dplyr’ idioms).
What’s Inside The Tin?
Lightweight helpers to make it easier to filter
and mutate
plus type
support for Athena BIGINT
(64-bit integers).
Installation
devtools::install_git("https://git.sr.ht/~hrbrmstr/metis-tidy")
# OR
devtools::install_gitlab("hrbrmstr/metis-tidy")
# OR
devtools::install_github("hrbrmstr/metis-tidy")
Usage
library(metis.tidy)
# current verison
packageVersion("metis.tidy")
## [1] '0.3.0'
Basic Setup (using an alternate provider)
