## Description

Read serialized Avro records as Logstash events
This plugin is used to serialize Logstash events as Avro datums, as well as deserializing Avro datums into Logstash events.

## Encoding

This codec is for serializing individual Logstash events as Avro datums that are Avro binary blobs. It does not encode Logstash events into an Avro file.

## Decoding

This codec is for deserializing individual Avro records. It is not for reading Avro files. Avro files have a unique format that must be handled upon input.

## Usage

Example usage with Kafka input.
```
input {
  kafka {
    codec => avro {
        schema_uri => "/tmp/schema.avsc"
    }
  }
}
filter {
  ...
}
output {
  ...
}
```
