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 Athenametis_jar_path()
: Retrieve the fully-qualified path to the included Athena JAR filesimba_driver_version
: Retrieve the version of the Simba Athena JDBC driver included with the package
