Caqti driver for MariaDB (bindings).

This driver is implemented in terms of the mariadb OPAM package. It handles URIs of the form mariadb://<user>:<password>@<host>:<port>/?<query> with the following query arguments:

  • socket=<socket> requests a UNIX domain socket connection
  • config-group=<name> loads additional settings from the section <name> of the default configuration file. Default: "caqti".

Except for the latter, options are passed to the correspondingly named arguments to the connect function of MariaDB. All parts of the URL are optional, except that the chosen combination must suffice to establish a connection.

The interface provided by this module should normally not be used by applications, but provides access to some MariaDB specifics in case they are needed.
