Class ChunkedValueManifest

java.lang.Object
org.apache.avro.specific.SpecificRecordBase
com.linkedin.venice.storage.protocol.ChunkedValueManifest
All Implemented Interfaces:
Externalizable, Serializable, 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.

    • keysWithChunkIdSuffix

      public List<ByteBuffer> keysWithChunkIdSuffix
      list of keys associated to all chunks. These are encoded with key + ChunkedKeySuffix appended at the end.

    • schemaId

      public int schemaId
      An identifier used to determine how the full value (after chunk re-assembly) can be deserialized. This is the ID of the user-defined schema.

    • size

      public int size
      The number of bytes of the entire value, once all chunks are assembled.

      public ChunkedValueManifest()
      Default constructor. Note that this does not initialize fields to their default values from the schema. If that is desired then one should use newBuilder().
