Connect to a DuckDB file.
Arguments
- dbdir
Location for database files. Should be a path to an existing directory in the file system. With the default (or ""), all data is kept in RAM.
- read_only
Set to TRUE for read-only operation. For file-based databases, this is only applied when the database file is opened for the first time. Subsequent connections (via the same drv object or a drv object pointing to the same path) will silently ignore this flag.
