Class ChunkedValueManifest

  • All Implemented Interfaces:
    java.io.Externalizable, java.io.Serializable, java.lang.Comparable<org.apache.avro.specific.SpecificRecord>, org.apache.avro.generic.GenericContainer, org.apache.avro.generic.GenericRecord, org.apache.avro.generic.IndexedRecord, org.apache.avro.specific.SpecificRecord

    public class ChunkedValueManifest
    extends org.apache.avro.specific.SpecificRecordBase
    implements org.apache.avro.specific.SpecificRecord
    This record maintains chunking information in order to re-assemble a value that was split in many chunks. The version of this schema is intentionally set to -1 because this is what will be used in the schema part of the value field, representing a special system-type schema, as opposed to a user-defined schema.
