Closing this as covered by the Sequence Feature Cookbook added in #554. See the Estimator and TFRecord Inputs section plus the DIN and BST History Feature Names section.

Docs: https://deepctr-doc.readthedocs.io/en/latest/Sequence-Cookbook.html

In short, prepare the same named tensors/features used by the DIN feature columns, including target sparse features, hist_ history sequence fields, and optional length fields when length_name is used.
