A parameter may either be a property of the event (i.e. "@timestamp", or "host") or a formatted string (i.e. "%{host} - %{message}" or "%{message}"). If a key is passed then it will be automatically converted as required for insertion into SQL. If it's a formatted string then it will be passed in verbatim. | Yes |  |

Failure to do so will result in possible SQL injections. Please be aware that there is also a potential performance penalty as each event must be evaluated and inserted into SQL one at a time, where as when this is false multiple events are inserted at once.

+  * Use the following configuration as a base. The connection_test => false and connection_test_query are very important and should not be omitted. Phoenix-thin does not appear to support isValid and these are necessary for the connection to be added to the pool and be available.
