Description

edit

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.

Partial deserialization

Avro format is known to support partial deserialization of arbitrary fields, providing a schema containing a subset of the schema which was used to serialize the data. This codec doesn’t support partial deserialization of arbitrary fields. Partial deserialization might work only when providing a schema which contains the first N fields of the schema used to serialize the data (and in the same order).

Usage

edit

Example usage with Kafka input.

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