Queue

NotifyBC uses BullMQ for notification processing, email and sms throttling. BullMQ is built on top of Redis. Redis connection is defined in config queue.connection with following defaults

module.exports = {
  // ...
  queue: {
    connection: {
      host: '127.0.0.1',
      port: 6379,
    },
  },
};

To override the defaults, set the config in src/config.local.js. More connection parameters are documented in ioredis. For example, to use Sentinel,

module.exports = {
  // ...
  queue: {
    connection: {
      sentinels: [{ host: process.env.REDIS_SERVICE_NAME }],
      name: 'mymaster',
      password: process.env.REDIS_PASSWORD,
      sentinelPassword: process.env.REDIS_PASSWORD,
    },
  },
};

If you deployed NotifyBC using Helm chart, this config is taken care of. If you deployed NotifyBC using docker, Redis is created inside docker using Redis In-Memory Server by default.
