##### SchemaRepo Based Avro Bytes Decoder
This Avro bytes decoder first extracts `subject` and `id` from the input message bytes, and then uses them to look up the Avro schema used to decode the Avro record from bytes. For details, see the [schema repo](https://github.com/schema-repo/schema-repo) and [AVRO-1124](https://issues.apache.org/jira/browse/AVRO-1124). You will need an http service like schema repo to hold the avro schema. For information on registering a schema on the message producer side, see `org.apache.druid.data.input.AvroStreamInputRowParserTest#testParse()`.

- Enabling `useFieldDiscovery` will only automatically detect "simple" fields at the root level that correspond to data types that Druid supports. This includes strings, numbers, and lists of strings or numbers. Other types will not be automatically detected, and must be specified explicitly in the `fields` list.
- Duplicate field `name`s are not allowed. An exception will be thrown.
- If `useFieldDiscovery` is enabled, any discovered field with the same name as one already defined in the `fields` list will be skipped, rather than added twice.

- [JSONPath evaluator](https://jsonpath.com/) is useful for testing `path`-type expressions.
- jackson-jq supports a subset of the full [jq](https://stedolan.github.io/jq/) syntax. Please refer to the [jackson-jq documentation](https://github.com/eiiches/jackson-jq) for details.
- [JsonPath](https://github.com/jayway/JsonPath) supports a bunch of functions, but not all of these functions are supported by Druid now. Following matrix shows the current supported JsonPath functions and corresponding data formats. Please also note the output data type of these functions.
