+\title{Create a (virtual) DuckDB table from an Arrow object}
+\usage{
+to_duckdb(
+  .data,
+  con = arrow_duck_connection(),
+  table_name = unique_arrow_tablename(),
+  auto_disconnect = FALSE
+)
+}
+\arguments{
+\item{.data}{the Arrow object (e.g. Dataset, Table) to use for the DuckDB table}
+
+\item{con}{a DuckDB connection to use (default will create one and store it
+in \code{options("arrow_duck_con")})}
+
+\item{table_name}{a name to use in DuckDB for this object. The default is a
+unique string \code{"arrow_"} followed by numbers.}
+
+\item{auto_disconnect}{should the table be automatically cleaned up when the
+resulting object is removed (and garbage collected)? Default: \code{FALSE}}
+}
+\value{
+A \code{tbl} of the new table in DuckDB
+}
+\description{
+This will do the necessary configuration to create a (virtual) table in DuckDB
+that is backed by the Arrow object given. No data is copied or modified until
+\code{collect()} or \code{compute()} are called or a query is run against the table.
+}
+\details{
+The result is a dbplyr-compatible object that can be used in d(b)plyr pipelines.
+
+If \code{auto_disconnect = TRUE}, the DuckDB table that is created will be configured
+to be unregistered when the \code{tbl} object is garbage collected. This is helpful
+if you don't want to have extra table objects in DuckDB after you've finished
+using them. Currently, this cleanup can, however, sometimes lead to hangs if
+tables are created and deleted in quick succession, hence the default value
+of \code{FALSE}
+}
