  13. def isClosed: Boolean

    Check if the serializer has been closed.

    Check if the serializer has been closed.

    It is illegal to used the serializer after it has been closed. It will lead to errors and sorts of undefined behavior.

  18. def reset(): Unit

    Reset the serializer.

  19. def sizeInBytes: Long

    The size of the current batch.

    The size of the current batch.

    The size computed consist of the size of the schema and the size of the arrow buffers. The actual batch will be larger than that because of alignment, written IPC tokens, and the written record batch metadata. The size of the record batch metadata is proportional to the complexity of the schema.
