adbcdrivermanager

The goal of adbcdrivermanager is to provide a low-level developer-facing interface to Arrow Database Connectivity (ADBC) for the purposes of driver development, testing, and support for user-facing packages that rely on ADBC drivers.

Installation

You can install the released version of adbcdrivermanager from CRAN with:

install.packages("adbcdrivermanager")

You can install the development version of adbcdrivermanager from GitHub with:

# install.packages("pak")
pak::pak("apache/arrow-adbc/r/adbcdrivermanager")

ADBC drivers for R use a relatively new feature of pkgbuild to enable installation from GitHub via pak. Depending on when you installed pak, you may need to update its internal version of pkgbuild.

install.packages("pkgbuild", pak:::private_lib_dir())
pak::cache_clean()

Example

This is a basic example which shows you how to solve a common problem:

library(adbcdrivermanager)

# Get a reference to a database using a driver. The adbcdrivermanager package
# contains a few drivers useful for illustration and testing.
db <- adbc_database_init(adbcsqlite::adbcsqlite())

# Open a new connection to a database
con <- adbc_connection_init(db)

# Write a table
nycflights13::flights |> write_adbc(con, "flights")

# Issue a query
con |>
  read_adbc("SELECT * from flights") |>
  tibble::as_tibble()

One can also interact with the driver manager at a lower level using adbc_connection_*() and adbc_statement_*() functions (see reference documentation for details).

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
