🐬MySQL

When using the MySQL app driver, first you should configure your MySQL connection credentials as environment variables:

Name	Default	Possible values	Description
SOKETI_DB_MYSQL_HOST	127.0.0.1	Any string	The MySQL host.
SOKETI_DB_MYSQL_PORT	3306	Any integer	The MySQL port.
SOKETI_DB_MYSQL_USERNAME	root	Any string	The MySQL username.
SOKETI_DB_MYSQL_PASSWORD	password	Any string	The MySQL password.
SOKETI_DB_MYSQL_DATABASE	main	Any string	The MySQL database.

This database supports database connection pooling.

Once you have configured your MySQL database credentials, you should create a table with the following structure:

CREATE TABLE IF NOT EXISTS `apps` (
    `id` varchar(255) NOT NULL,
    `key` varchar(255) NOT NULL,
    `secret` varchar(255) NOT NULL,
    `max_connections` integer(10) NOT NULL,
    `enable_client_messages` tinyint(1) NOT NULL,
    `enabled` tinyint(1) NOT NULL,
    `max_backend_events_per_sec` integer(10) NOT NULL,
    `max_client_events_per_sec` integer(10) NOT NULL,
    `max_read_req_per_sec` integer(10) NOT NULL,
    `webhooks` json,
    `max_presence_members_per_channel` tinyint(1) NULL,
    `max_presence_member_size_in_kb` tinyint(1) NULL,
    `max_channel_name_length` tinyint(1) NULL,
    `max_event_channels_at_once` tinyint(1) NULL,
    `max_event_name_length` tinyint(1) NULL,
    `max_event_payload_in_kb` tinyint(1) NULL,
    `max_event_batch_size` tinyint(1) NULL,
    `enable_user_authentication` tinyint(1) NOT NULL,
    PRIMARY KEY (`id`)
);

Environment Variables

The following environment variables are used to define the behavior of the MySQL app driver:

Name	Default	Possible values	Description
SOKETI_APP_MANAGER_MYSQL_TABLE	apps	Any string	The table to pull the app data from.
SOKETI_APP_MANAGER_MYSQL_VERSION	8.0	Any string	The MySQL version (utilized by the underlying Knex database abstraction layer).
SOKETI_APP_MANAGER_MYSQL_USE_V2	false	true, false	soketi 0.14+. If you're using MySQL 8.0+ and experience authentication issues, you may enable this option.

Limits on an app-by-app basis

To enforce app-level limits in MySQL, there are multiple fields:

`max_presence_members_per_channel` tinyint(1) NULL,
`max_presence_member_size_in_kb` tinyint(1) NULL,
`max_channel_name_length` tinyint(1) NULL,
`max_event_channels_at_once` tinyint(1) NULL,
`max_event_name_length` tinyint(1) NULL,
`max_event_payload_in_kb` tinyint(1) NULL,
`max_event_batch_size` tinyint(1) NULL

Setting any of them to null or '' will ignore the setting, and use the limits associated with the server-level declared defaults.
