PostgreSQL
When using the PostgreSQL app driver, first configure your PostgreSQL connection credentials using environment variables:
Name | Default | Possible values | Description |
|---|---|---|---|
SOKETI_DB_POSTGRES_HOST | 127.0.0.1 | Any string | The PostgreSQL host. |
SOKETI_DB_POSTGRES_PORT | 3306 | Any integer | The PostgreSQL port. |
SOKETI_DB_POSTGRES_USERNAME | root | Any string | The PostgreSQL username. |
SOKETI_DB_POSTGRES_PASSWORD | password | Any string | The PostgreSQL password. |
SOKETI_DB_POSTGRES_DATABASE | main | Any string | The PostgreSQL database. |
Once you have configured your PostgreSQL database credentials, you should create a table with the following structure:
CREATE TABLE IF NOT EXISTS apps (
id varchar(255) PRIMARY KEY,
"key" varchar(255) NOT NULL,
secret varchar(255) NOT NULL,
max_connections integer NOT NULL,
enable_client_messages smallint NOT NULL,
"enabled" smallint NOT NULL,
max_backend_events_per_sec integer NOT NULL,
max_client_events_per_sec integer NOT NULL,
max_read_req_per_sec integer NOT NULL,
max_presence_members_per_channel integer DEFAULT NULL,
max_presence_member_size_in_kb integer DEFAULT NULL,
max_channel_name_length integer DEFAULT NULL,
max_event_channels_at_once integer DEFAULT NULL,
max_event_name_length integer DEFAULT NULL,
max_event_payload_in_kb integer DEFAULT NULL,
max_event_batch_size integer DEFAULT NULL,
webhooks json,
enable_user_authentication smallint NOT NULL
);
The following environment variables are used to define the behavior of the PostgreSQL app driver:
Name | Default | Possible values | Description |
|---|---|---|---|
SOKETI_APP_MANAGER_POSTGRES_TABLE | apps | Any string | The table to pull the app data from. |
SOKETI_APP_MANAGER_POSTGRES_VERSION | 13.3 | Any string | The PostgreSQL version (utilized by the underlying Knex database abstraction layer). |
To enforce app-level limits in PostgreSQL, there are multiple fields:
max_presence_members_per_channel integer DEFAULT NULL,
max_presence_member_size_in_kb integer DEFAULT NULL,
max_channel_name_length integer DEFAULT NULL,
max_event_channels_at_once integer DEFAULT NULL,
max_event_name_length integer DEFAULT NULL,
max_event_payload_in_kb integer DEFAULT NULL,
max_event_batch_size integer DEFAULT NULL
Setting any of them to
null or '' will ignore the setting, and use the limits associated with the server-level declared defaults.Last modified 11mo ago
