avro

  • Version: 3.0.0
  • Released on: 2016-09-08
  • Changelog

This plugin does not ship with Logstash by default, but it is easy to install by running bin/logstash-plugin install logstash-codec-avro.

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

edit

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

edit

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

edit

Example usage with Kafka input.

input {
  kafka {
    codec => avro {
        schema_uri => "/tmp/schema.avsc"
    }
  }
}
filter {
  ...
}
output {
  ...
}
