| autocreate   | boolean | false    | false   | if true, then we will create the table. Defaults to false (Optional)                     |

The columns needed or created in the table are

* `id` : UUID
* `severity` : string
* `category` : string
* `logdate` : timestamp

* `message` : string
* `extrainfo` : string

If you are building a column mapper, the map must have the above keys in it that match to your own table columns.
