An implementation of the Electrode OTA Server's data access layer using MariaDB as a back-end.

Usage

In your electrode ota server implementation, include this module as a dependency.

npm install --save electrode-ota-server-dao-mariadb

Update your OTA server configuration to override the DAO plugin. This is assuming your config is in JavaScript format (not JSON).

const conf = {
    plugins : {
        // ...

        "electrode-ota-server-dao-plugin" : {
            module : "electrode-ota-server-dao-mariadb",
            // connection options based on typeorm;
            // 'type' and 'entities' are defaulted but may be overriden
            options : {
                clusterConfig : {
                    canRetry : true,
                    defaultSelector : "ORDER",
                    removeNodeErrorCount : 5,
                    restoreNodeTimeout : 0,
                },
                poolConfigs : [{
                    database: "bento_ota",
                    host: "localhost",
                    password: "password",
                    port: 3306,
                    user: "user",
                }],
            }
        },

        // ...
    }
}

The clusterConfig is the settings for the mysql PoolCluster options.

The poolConfigs property is an array of Connection options.
