Usage

rducks_native_execution_backend(con)

Arguments

con

A duckdb_connection already enabled with rducks_enable().

Value

Character scalar backend name: "single", "concurrent_inproc", or "multiprocess_parallel".

Examples

# \donttest{
db <- duckdb::dbConnect(duckdb::duckdb(config = list(allow_unsigned_extensions = "true")))
rducks_enable(db)
rducks_native_execution_backend(db)
#> [1] "single"
rducks_release(db)
DBI::dbDisconnect(db)
# }
