Add required parameters to [Django settings.py](https://docs.djangoproject.com/en/3.0/topics/settings/):
|

1. [CLICKHOUSE_DATABASES](configuration.md#clickhouse_databases)
|
||||
2. [Intermediate storage](storages.md) configuration. For instance, [RedisStorage](storages.md#redisstorage)
|
||||
3. It's recommended to change [CLICKHOUSE_CELERY_QUEUE](configuration.md#clickhouse_celery_queue)
|
||||
4. Add sync task to [celerybeat schedule](http://docs.celeryproject.org/en/v2.3.3/userguide/periodic-tasks.html).

Sync time depends on model sync_delay attribute value and [CLICKHOUSE_SYNC_DELAY](configuration.md#clickhouse_sync_delay) configuration parameter.
