Connecting R and CrateDB with ADBC

Instructions

Tip

If you already have a CrateDB instance running, skip the steps to set up and clean up CrateDB.

Install R packages adbcdrivermanager, arrow, and tibble:

install.packages(c("adbcdrivermanager", "arrow", "tibble"))

Start a CrateDB instance:

docker run -d --rm --name cratedb -p 4200:4200 -p 5432:5432 crate -Cdiscovery.type=single-node

Install the PostgreSQL ADBC driver:
```
dbc install postgresql
```
Customize the R script main.R as needed
- Change the connection arguments in adbc_database_init()
  - Format uri according to the connection URI format used by PostgreSQL, or keep it as is
- If you changed which database you're connecting to, also change the SQL SELECT statement in read_adbc()
Run the R script:
```
Rscript main.R
```

Stop the Docker container running CrateDB:

docker stop cratedb
