Amazon Athena JDBC Driver Wrapper Supporting the ‘metis’ Package

#Description

Contents of the Amazon Athena JDBC Driver https://docs.aws.amazon.com/athena/latest/ug/connect-with-jdbc.html provided to support functions in the ‘metis’ package. Version number reflects the version number of the included ‘JAR’ file.

#IMPORTANT

Until a release of ‘rJava’ newer than ‘0.9.10’ is on CRAN signals sent from interrupting Athena JDBC calls crash the R interpreter. You therefore 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:

options(
  "java.parameters" = c(getOption("java.parameters", default = NULL), "-Xrs")
)

#What’s Inside The Tin?

The following functions are implemented:

• athena_supported_types: Retrieve the current supported type names in Athena
• metis_jar_path() : Retrieve the fully-qualified path to the included Athena JAR file
• simba_driver_version: Retrieve the version of the Simba Athena JDBC driver included with the package
