The goal of adbcpostgresql is to provide a low-level developer-facing interface to the Arrow Database Connectivity (ADBC) PostgreSQL driver.
You can install the released version of adbcpostgresql from CRAN with:
You can install the development version of adbcpostgresql from GitHub with:
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.
This is a basic example which shows you how to solve a common problem:
library(adbcdrivermanager)
# Use the driver manager to connect to a database
uri <- Sys.getenv("ADBC_POSTGRESQL_TEST_URI")
db <- adbc_database_init(adbcpostgresql::adbcpostgresql(), uri = uri)
con <- adbc_connection_init(db)
# Write a table
nycflights13::flights |> write_adbc(con, "flights")
# Issue a query
con |>
read_adbc("SELECT * from flights") |>
