+== Configure AVRO Schema Handler
+
+The AVRO schema handler is added to the configuration as follows:
+
+[source%nowrap,json]
+----
+"engineServiceParameters":{
+ "engineParameters":{
+ "contextParameters":{
+ "parameterClassName" : "org.onap.policy.apex.context.parameters.ContextParameters",
+ "schemaParameters":{
+ "Avro":{
+ "parameterClassName" :
+ "org.onap.policy.apex.plugins.context.schema.avro.AvroSchemaHelperParameters"
+ }
+ }
+ }
+ }
+}
+----
+
+Using the AVRO schema handler has one limitation: AVRO only supports field names that represent valid Java class names.
+This means only letters and the character `_` are supported.
+Characters commonly used in field names, such as `.` and `-`, are not supported by AVRO.
+for more information see link:https://avro.apache.org/docs/1.8.1/spec.html#names[Avro Spec: Names].
+
+To work with this limitation, the APEX Avro plugin will parse a given AVRO definition and replace _all_ occurrences of `.` and `-` with a `_`.
+This means that
+
+- In a policy model, if the AVRO schema defined a field as `my-name` the policy logic should access it as `my_name`
+- In a policy model, if the AVRO schema defined a field as `my.name` the policy logic should access it as `my_name`
+- There should be no field names that convert to the same internal name
+ ** For instance the simultaneous use of `my_name`, `my.name`, and `my-name` should be avoided
+ ** If not avoided, the event processing might create unwanted side effects
+- If field names use any other not-supported character, the AVRO plugin will reject it
+ ** Since AVRO uses lazy initialization, this rejection might only become visible at runtime
