Class GenericAvroSerializer<D extends org.apache.avro.generic.GenericContainer>

java.lang.Object

com.esotericsoftware.kryo.Serializer<D>

org.apache.hudi.avro.GenericAvroSerializer<D>

Type Parameters:

D - the subtype of [[GenericContainer]] handled by this serializer

public class GenericAvroSerializer<D extends org.apache.avro.generic.GenericContainer>
extends com.esotericsoftware.kryo.Serializer<D>

Custom serializer used for generic Avro containers.

Heavily adapted from:

GenericAvroSerializer.scala

As SerializationUtils is not shared between threads and does not concern any shuffling operations, compression and decompression cache is omitted as network IO is not a concern.

Unlike Spark's implementation, the class and constructor is not initialized with a predefined map of avro schemas. This is the case as schemas to read and write are not known beforehand.
