#' Methods are provides to connect to 'Amazon' 'Athena', lookup schemas/tables,
|
|
|
|
|
#' perform queries and retrieve query results. A lightweight 'RJDBC' implementation
|
|
|
|
|
#' is included along with an interface to the 'AWS' command-line utility.

#' Since R 3.5 (I don't remember this happening in R 3.4.x) signals sent from interrupting
|
|
|
|
|
#' Athena JDBC calls crash the R #' interpreter. You need to set the `-Xrs` option to avoid
|
|
|
|
|
#' signals being passed on to the JVM owner. That has to be done _before_ `rJava` is
|
|
|
|
|
#' loaded so you either need to remember to put it at the top of all scripts _or_ stick this
|
|
|
|
|
#' in your local #' `~/.Rprofile` and/or sitewide `Rprofile`:
