      Deprecated.
      will be removed in 2.0.0; use create(org.apache.iceberg.Schema, Function, Schema) instead
      Creates a new MessageDecoder that constructs datum instances described by the readSchema.

      The readSchema is used for the expected schema and the writeSchema is the schema used to decode buffers. The writeSchema must be the schema that was used to encode all buffers decoded by this class.

    • create

      public static <D> RawDecoder<D> create(Schema readSchema, Function<Schema,org.apache.avro.io.DatumReader<D>> readerFunction, org.apache.avro.Schema writeSchema)
      Creates a new MessageDecoder that constructs datum instances described by the readSchema.

      The readSchema is used for the expected schema and the writeSchema is the schema used to decode buffers. The writeSchema must be the schema that was used to encode all buffers decoded by this class.

      Parameters:
      readSchema - an Iceberg schema to produce when reading
      readerFunction - a function that produces a DatumReader from the read schema
      writeSchema - an Avro schema that describes serialized data to be read
