Package org.apache.beam.sdk.extensions.avro.schemas

Class AvroRecordSchema

  • All Implemented Interfaces:
    java.io.Serializable, org.apache.beam.sdk.schemas.SchemaProvider
    public class AvroRecordSchema
extends org.apache.beam.sdk.schemas.GetterBasedSchemaProviderV2
    A SchemaProvider for AVRO generated SpecificRecords and POJOs.

    This provider infers a schema from generated SpecificRecord objects, and creates schemas and rows that bind to the appropriate fields. This provider also infers schemas from Java POJO objects, creating a schema that matches that inferred by the AVRO libraries.
