Serve the current session over Quack

Starts a Quack server in the current DuckDB instance. Everything attached to the session, including a DuckLake attached with attach_ducklake(), becomes reachable by other DuckDB clients over the quack: protocol. The server runs in the background of the DuckDB instance, so the R session stays usable.

Usage

quack_serve(
  uri = "quack:localhost",
  token = NULL,
  allow_other_hostname = FALSE,
  disable_ssl = FALSE
)

Arguments

uri

Address to listen on (default "quack:localhost"). The default port is 9494.

token

Authentication token that clients must supply. If NULL, the server accepts any client that can reach it, and a warning is issued.

allow_other_hostname

Accept connections addressed to a hostname other than the one in uri (default FALSE).

disable_ssl

Serve over plain HTTP instead of HTTPS (default FALSE). Only appropriate on a trusted network.

Value

The server uri, invisibly.
