You need to extend the collector service:

// app/services/my-collector.js

export default Collector.extend({
  adapters: [
    ['indexed-db', { database: 'logs' }],
    ['local-storage', { key: 'logs' }],
    'memory'
  ]
});

You also need to define adapters with the possible storages. Now, you can choose: indexeddb, local-storage and memory.

  maxTimeout: 30000,
  maxConcurrent: 5,

  async dispatch(items) {
