## Logs auto deletion

It is possible to run streams logs auto deletion. This is needs to clean the database from a large number of unnecessary records. The most recent record for each stream will not be deleted.

You can configure logs auto deletion by LUNA_STREAMS_LOGS_CLEAR_INTERVAL setting.

> - interval - Integer. Logs older than interval will delete.

> - interval_type - String. Type of interval (“weeks”, “days”, “hours”, “minutes”, “seconds”)

> - check_interval - Integer. In seconds. How often background task will check logs for deletion.

> - active - Boolean. If set to true logs auto deletion will be enabled, otherwise will not.

By default auto deletion stopped. For example default setting values run auto deletion with check streams logs in data base each 180 seconds and delete logs older than 7 days.

For example if it needs to check each 5 minutes for delete logs older than 4 weeks, set values below:

    {
        "interval": 4,
        "interval_type": "weeks",
        "check_interval": 300,
        "active": true
    }
