-== 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
