[GitHub] [beam] damccorm opened a new issue, #19721: Add Schema support for Tensorflow

damccorm opened a new issue, #19721:
URL: https://github.com/apache/beam/issues/19721

   Similar to BEAM-5807, Tensorflow's defacto storage format is `TFRecord` files with `Example` proto payload and its own schema.proto. We already have `TFRecordIO` support. Need to implement:
    * Conversion between Beam and TF schema
    * Conversion between Beam Row and TF Example proto
    * `TFRecordTableProvider`

   Also it seems the metadata protos are not published as Java artifacts:
