#summary XEP-0313: Message Archive Management using SQL

= Introduction =

Implementation of [http://xmpp.org/extensions/xep-0313.html XEP-0313: Message Archive Management] backed by a SQL database.  Like [mod_mam], but using SQL.


= Details =

See [mod_mam] for details.

= Usage =

First copy the module to the prosody plugins directory.

Then add "mam_sql" to your modules_enabled list:
{{{
    modules_enabled = {
                    -- ...
                    "mam_sql",
                    -- ...
		}
}}}

You should probably run the SQL to create the archive table/indexes:

{{{
CREATE TABLE `prosodyarchive` (
        `host` TEXT,
        `user` TEXT,
        `store` TEXT,
        `id` INTEGER PRIMARY KEY AUTOINCREMENT,
        `when` INTEGER,
        `with` TEXT,
        `resource` TEXT,
        `stanza` TEXT
);
CREATE INDEX `hus` ON `prosodyarchive` (`host`, `user`, `store`);
CREATE INDEX `with` ON `prosodyarchive` (`with`);
CREATE INDEX `thetime` ON `prosodyarchive` (`when`);
}}}

(*NOTE*: I ran the following SQL to initialize the table/indexes on MySQL):

{{{
CREATE TABLE prosodyarchive (
  `host`     VARCHAR(16) NOT NULL,
  `user`     VARCHAR(16) NOT NULL,
  `store`    CHAR(8)     NOT NULL,
  `id`       INTEGER PRIMARY KEY AUTO_INCREMENT,
  `when`     INTEGER     NOT NULL,
  `with`     VARCHAR(32) NOT NULL,
  `resource` VARCHAR(16) NOT NULL,
  `stanza`   TEXT        NOT NULL
);
CREATE INDEX hus ON prosodyarchive (host, user, store);
CREATE INDEX `with` ON prosodyarchive (`with`);
CREATE INDEX thetime ON prosodyarchive (`when`);
}}}

You may want to tweak the column sizes a bit; I did for my own purposes.

= Configuration =

This module uses the same configuration settings that [mod_mam] does, in addition to the [http://prosody.im/doc/modules/mod_storage_sql SQL storage settings].  You may also name the SQL connection settings 'mam_sql' if you want.
