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}").

-**There are special instructions for phoenix-thin. Please read carefully!**
-
-  * Tested with Logstash 5.1.1 / Apache Phoenix 4.9
-  * HBase and Zookeeper must be both accessible from logstash machine
-  * At time of writing phoenix-client does not include all the required jars (see https://issues.apache.org/jira/browse/PHOENIX-3476), therefore you must *not* use the driver_jar_path configuration option and instead:
-    - `mkdir -p vendor/jar/jdbc` in your logstash installation path
-    - copy `phoenix-queryserver-client-4.9.0-HBase-1.2.jar` from the phoenix distribution into this folder
-    - download the calcite jar from https://mvnrepository.com/artifact/org.apache.calcite/calcite-avatica/1.6.0 and place it into your `vendor/jar/jdbc` directory
-  * 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.
